I bought several 4-year-old fruit saplings online, including cherries, apples, and peaches. They were just transplanted into flower pots. Do these saplings need to be watered every day?

No need to water like this. The following is written by Baihua Information Network

Cherry trees grow rapidly, with obvious and concentrated development stages. The growth of branches and leaves, flowering and fruit setting are all concentrated in the first half of the growing season, and flower bud differentiation is mostly completed within a short period of time after fruit picking. It takes about 50 days from flowering to harvest for Chinese cherries and 60 days for sweet (large) cherries. For this reason, fertilizer should be applied early according to the characteristics of cherries, and good base fertilizer, flower fertilizer and post-fruit fertilizer should be paid attention to. Generally speaking, the amount of nitrogen fertilizer should be small, the proportion of phosphorus and potassium fertilizer should be large, and the amount of organic fertilizer should be more.

Basal fertilizer should be applied early in autumn, no later than November. Fertilizer, human and animal urine, and soil fertilizers can all be applied. Generally, 30 to 60 kilograms of human and animal manure or 100 kilograms of pen fertilizer are applied to saplings and trees in the early fruiting stage; 60 to 80 kilograms of human and animal manure or 200 kilograms of pen fertilizer are applied to mature trees.

Top dressing should be done before flowering or during the first period of fruit growth, mainly with fast-acting nitrogen fertilizer, which can increase the fruit setting rate, promote branch growth and leaf hypertrophy, and lay a good foundation for flower bud differentiation. If the leaves are sprayed with 0.5 urea 1 to 2 times in the early blooming stage, and 0.5 boron fertilizer or 600 times potassium dihydrogen phosphate is added, the fruit setting rate can be increased.

Supplementary fertilizer Supplementary fertilizer after fruit harvesting can increase the tree's nutrient reserves and promote flower bud differentiation. After picking the fruit, the fruit tree changes from the nutrient consumption stage of flowering, fruiting, branching and leaf expansion to the nutrient accumulation stage and begins to enter the qualitative change stage of flower bud differentiation. Therefore, the main types of supplementary fertilizers are quick-acting fertilizers, such as decomposed human excrement, soybean cakes and chemical fertilizers. The amount of fertilizer applied can be determined according to the age of the tree, the size of the crown and the number of fruits. Generally, 60 to 80 kilograms of decomposed human excrement, 2.5 to 3 kilograms of decomposed bean cakes, 1.5 kilograms of ammonium sulfate, or 0.5 to urea are applied to the tree. 1kg. It can also be applied as a foliar spray.

The management methods of apple trees in July are:

Drainage and weeding during the rainy season

The climate in July is characterized by high temperature and rainy weather. When there is too much water in the orchard soil, the growth and absorption of the roots will be inhibited due to poor ventilation. Therefore, drainage channels should be dredged before the rainy season, plowing and weeding should be carried out promptly after the rain, and young orchards can be plowed deeply to facilitate root growth. For waterlogged plants, the root neck should be stripped of soil and dried to help the root system recover as soon as possible.

Green manure rolling in orchards and tree protection

Generally, 40 to 60 kilograms of fresh grass per tree for young trees and 120 to 150 kilograms for large and weak trees are used for green manure rolling. If the green manure branches and leaves are aging, a small amount of quick-acting nitrogen fertilizer, superphosphate or compound fertilizer should be applied in the green ditch. Fruit trees with too many fruits and fruit parts that have moved outwards should be hung and top branches to avoid branch damage. For middle trunk trees, the umbrella-shaped branch hanging method is generally used, that is, the upper part of the central trunk is used as a fulcrum, and a straw rope is tied. The other end of the straw rope leads to the backbone branches or large branch groups at all levels that need to be lifted, and is placed outside the distance. The top 2/5 of the tree is tied to form an umbrella shape; for open-shaped trees without a central trunk, or larger branches with drooping branches, they can be supported by pillars such as wooden sticks, and the position of the support should be outside the middle of the branch. After the fruit is harvested, the slings should be removed in time, combined with clearing the garden, to eliminate the overwintering places for pathogens and pests.

Key points of management of apple trees in August

Apple trees (fruit expansion period): ①Pruning: Displace young and long branches to slow growth; remove competing branches in a timely manner , shading branches, multi-headed branches, diseased and insect-infested branches, etc., to improve light, control branch potential, and promote flower bud differentiation. ②Soil, fertilizer and water: loosen the soil and weed the orchard. For late-maturing varieties, spray 0.5% potassium dihydrogen phosphate and calcium fertilizer on the leaves in combination with spraying. ③Harvesting: Harvest medium-ripe varieties. ④Pest control: Spray 68.75 easy-to-retain water-dispersible granules 1200 times liquid (or 50 ethanol wettable powder 800 times liquid) and 25 chloride urea No. 3 1200 times liquid in the first and middle of the month to prevent ring fruit rot and spotted leaf fall disease. , golden streak moth, cotton bollworm, etc. Spray 1:2:180 Bordeaux mixture and 30% peach Xiaoling EC 1500 times in the middle and late stages to prevent ring rot, brown spot, peach heartworm, cotton bollworm, etc.

Pick diseased fruits and process them together

Peach

Basal fertilizer is recommended to be applied in winter and autumn, mainly organic fertilizer, accounting for 60 to 70% of the annual fertilizer application, generally applied per mu 2000kg of stable fertilizer or 150kg of special fertilizer for fruit trees per acre; the frequency, time and dosage of topdressing vary according to the species, tree age, cultivation and management methods, growth and development period and external conditions. Generally, pre-emergent fertilizer, fruit-strengthening fertilizer and Mainly post-harvest fertilizer.

4. Plastic pruning

(1) Tree shape and tree structure: The tree shape is a natural open heart shape with three main branches. The tree structure, the height of the adult tree is maintained at 2. Peach (18 photos) is about 5 to 3 meters, with a stem height of 30 to 40 centimeters, and three main branches, each occupying an azimuth angle of 120°, and each main branch is equipped with 1 to There are 2 sub-main branches with an opening angle of about 75°.

(2) Tree-shaped cultivation: Set the stem at 50 to 60 cm in the year of planting, and there must be more than 3 strong buds in the shaping band under the cut. In the first year of growth after planting, select new shoots with stronger growth and better azimuth angles and cultivate them as main branches. The remaining new shoots can be thinned out or twisted as auxiliary branches. In the second year after planting, select strong lateral branches at a distance of 50 to 60 cm from the main trunk, with a good opening angle, and cultivate secondary main branches. At the same time, cultivate large and small fruiting branch groups on the main branches and secondary main branches.

(3) Pruning: Pruning during the dormant period (winter). It can be carried out after the leaves fall and before germination. Pruning adopts a combination of short cutting and thinning, as well as long planting, retraction, and ringing of branches. Pruning of fruiting branches: For long fruiting branches, cut off about one-third of the branch length; for medium-fruiting branches, except for sparse pruning of dense branches, generally do not cut short; for short-fruiting branches, one branch should be kept every 10 centimeters or so. The amount of branches left depends on site conditions, management level, tree age, tree vigor and yield requirements. Pruning during the growth period mainly includes technical measures such as re-pruning after flowering, removing buds, thinning branches, twisting branches, topping, pulling branches, pruning tips, and moving branches.

5. Fruit management

Peach has a high fruit setting rate, so fruit thinning must be carried out to control the amount of fruit left. Fruit thinning should be carried out in two times, one in late April to the other in early May and one in mid-to-late May. Generally, one fruit will be left on short fruit branches, two fruits on medium fruit branches, and 3 to 5 fruits on long fruit branches. After the fruit is set, spray and bag in time. The fruit harvesting period depends on the characteristics of the variety, and it is appropriate to harvest 80% mature fruits.

6. Prevention and control of diseases and insect pests

To prevent and control diseases, we must first do a good job in clearing the garden in winter, and remove diseased branches and leaves in time in combination with winter pruning; whiten the trunks before and after the beginning of winter; before budding in early spring Spray Baume 5 degree lime sulfur mixture to prevent and control brown rot, anthracnose, scab, leaf shrinkage and other diseases during the growth period. Pests that harm peach trees include aphids, pear heartworms, small green leafhoppers, peach borers, stinging moths, armyworms, white mulberry scales, etc. Spray pesticides in a timely manner according to the occurrence.
