Many weeds grow under the plum tree. How should I loosen the soil?

Plum is a very common fruit in the market, and its varieties are also very rich, such as rock sugar plum, bee sugar plum, crisp red plum and so on. Plum is crisp and tender, with high nutritional value, which is very common in southern China. However, with the gradual recovery of spring, plums in some areas are busy with marketing. In order to increase the sales yield of plums, weeding is also very important. So how do plum trees weed? Let's get to know each other.

1. Dig and loosen the soil.

It is hot and rainy in spring and summer, and the humidity in the field is high. Weeds grow quickly under plum trees. Because plum trees are not very deep, weeds can easily compete with plum trees for nutrition. Therefore, on plum trees, after fruit picking, the orchard should be thoroughly loosened, and the depth of loosening soil is generally required to be about 30 cm. Then, every plum tree should be fully applied with manure, compost, weeds and so on. This can kill two birds with one stone by weeding and increasing soil fertility.

2. Pest control

Weeding should be accompanied by pest control. There are many diseases and pests in plum trees, and weeds are also hiding places for many germs. If pests such as stem borers, gummosis and aphids are found, corresponding prevention and control management should be done to avoid affecting plant growth. Gummosis can be sprayed once before germination or 2-3 times after germination; The peach fruit borer can be controlled by dichlorvos, killing the enemy after flowering, pure alcohol. Aphids can be sprayed with dichlorvos emulsion and dimethoate emulsion, and can also be controlled with dichlorvos.

3. Chemical weeding

If weeds appear in the plum garden, 250 ml of 20% paraquat can be added to 45 kg of water per mu and sprayed on the ground. If weeds are very lush, 200-400 ml of 4 1% double-fire herbicide (according to the number of weeds) and 30 kg of strong assistant can be sprayed on the ground weeds. Herbicide is an endogenous conductive herbicide. Spray evenly and thoroughly. Weeds usually die within 7- 15 days, which can kill the roots of weeds.

4. Nutritional supplement

Weeds will rob plum trees of some nutrients, so special attention should be paid to supplementing fertilizer after weeding. Especially after harvest, one-time fertilization is needed, mainly to improve the assimilation function of trees, supplement the nutrition of trees, and ensure that plum trees have sufficient nutritional support after this harvest. Generally, 250g of urea, 250g of potassium fertilizer and 0/.5-2.5kg of calcium superphosphate/kloc-0 are applied to each plant.

Generally speaking, weed control of plum trees is an important part of plum tree planting management. Like other fruit trees, attention should be paid to insect prevention and fertilization while weeding. In fact, the overall technical requirements are not complicated, and the key is to master the time and the use of drugs.
