What is the best medicine to use to light tomatoes?

Tomato growers all know that severe flower and fruit drop in the early stage of planting tomatoes will lead to low tomato yield in the later stage. So an important part of high tomato yield is: preserving flowers and fruits. The methods used by vegetable farmers are nothing more than these four: tomato flowering, flower dipping, flower spraying, and bumble bee pollination. Which of these four methods is the best? Let me tell you in detail today. 1. Tomato flower spotting

Tomato flower spotting is the most commonly used method for tomato farmers to pollinate tomato flowers. Use a cotton swab to dip a little of the red potion (anther potion) in the bottle, and then apply it to the tomato flowers. of the petiole.

Artificial pollination of tomatoes is definitely a technical job. If you add too much medicine, the tomatoes produced in the future will crack. If you add too little medicine, the flowers will wither, which will affect the yield of tomatoes.

Generally, 5 or 6 tomato flowers will bloom on one petiole, but the flower opening time is different. It takes several days for a tomato flower to bloom, and people have to bend over and over again. Look for flowers that have bloomed late and have not yet bloomed to pollinate them. If it is missed, the flower will bloom in vain and bear no fruit.

You have to bend down all the time to pollinate tomatoes. After a long time, your tired back hurts and you can’t stand up straight. Constantly bending down to pollinate flowers, while getting a good harvest, it also suffered from lumbar muscle strain.

Notes:

1. Dip tomatoes into flowers. There are many flower buds, so don’t dip them in a hurry. Dip them when the first flower falls. Don’t dip them in half. The fruits are uneven.

2. When tomatoes are in peak flowering stage, plant them every two days. Order big flowers. 2. Dip tomatoes into flowers

To dip tomatoes into flowers, put the entire flower spike of tomatoes in a bowl or other small container with liquid medicine and dip it.

Dipping flowers is less labor-intensive and simpler than dotting flowers.

There are many disadvantages of dipping flowers:

1. The amount of liquid medicine attached to the entire flower spike is much larger when dipping flowers than dotting and spraying flowers. After flowering, more nutrients in the tomato plants are transported to the flowers. The growth of the tomato plants will weaken, the leaves will turn yellow, and abscisic acid in the body will increase, causing flower and fruit drop.

2. General anther dippers are systemic, and hormone poisoning is likely to occur when a certain amount accumulates in the plant.

3. Dipping flowers sometimes also dips undeveloped flowers and flowers that are about to bloom, resulting in the production of a large number of dead fruits. Moreover, the fruits vary in size and the spermatozoa rate is low.

3. After dipping the flowers, the liquid in the flower spikes can easily drip on the leaves, affecting the growth of the leaves. 3. Spray tomatoes

To spray tomatoes, use a small sprayer to spray anthers (anti-falling agent, fruit-setting agent) on the back of the tomato flower, that is, the flower stalk and calyx, rather than spraying on the petals. superior.

Specific method: The first spray should be carried out when 3-4 flowers are open in the flower spike. At this time, it is best to spray from the inside to the outside of the tomato. The amount of spray should be small to avoid spraying on the leaves. , and at the same time, use your gloved left hand to block the unopened flowers on the outermost side of the inflorescence to avoid spraying on the unopened flowers;

When 3-4 more flowers bloom, spray them for the second time. The spraying direction should be opposite to the first spraying direction, spray from the outside to the inside, and use your gloved left hand to block the flowers that have been sprayed on the inside, and block the medicine liquid on your gloves to avoid spraying the flowers that have been sprayed. and on the leaves.

Flower spraying period: When spraying flowers, pay attention to the opening of the flowers. Generally, start spraying when three or four branches are in bloom. Do not spray too late or too early. Early stiffness and late cracking.

Temperature when spraying flowers: Based on the weather and the temperature in the shed, choose a temperature of 20-25℃ for the best spraying effect.

In spring from March to April, 9:00-10:00 am or 3:00-4:00 pm is best.

Do not spray if the temperature is too high or too low. If the concentration is too low, the effect will be insignificant. If the concentration is too high, deformed fruits and hollow fruits may appear.

Spraying interval: the number of days between spraying and dropping, every 5-6 days in early spring when the temperature is low. Generally, the wilting of the flowers can be seen in the last flower spraying, and the fruit begins to swell and set. , and then spray the next time, so as to avoid repeated spraying.

Master the concentration of anther spray: too low a concentration will have no significant effect, and too high a concentration may cause deformed or hollow fruits. The concentration should also change with changes in external temperature. Generally speaking, the lower limit of concentration is used at high temperatures and the high limit is used at low temperatures.

Notes:

1. Before spraying flowers, thin out the flowers first and remove the first flower of each spike, because this flower usually blooms two days earlier than the following flowers. On the left and right, the fruit of this flower has a relatively large proportion of deformities. In addition, after it becomes the main fruit, it competes for nutrients and will grow very large, which will affect the growth of other fruits, that is, it will remove its apical advantage
