Recently, many vegetable farmers have reported that there are many problems in the fruits of the tomatoes in the autumn shed, and these problems occur in the occurrence of regularity in the ear: the first ear has more fruit, and the third and fourth ear have more empty ears; The hollow fruit in the upper ear is particularly large.
common problem
The first fruit and more fruit
There are many causes of tomato unsteady fruit, but there are two main reasons that cause the first fruit to have a lot of stale fruit:
(1) Poor flower bud differentiation. Tomato flower bud differentiation is early and fast, generally when the seedlings have 2-3 true leaves, the flower bud differentiation of the first spike flower is carried out, and when 4-5 true leaves are differentiated, the second spike flower bud is differentiated. This period of time is in the hot season of August and September. The temperature of the shed is often higher than 35°C, resulting in poor flower bud differentiation and high probability of staleness.
(2) It takes too little time. If you spend time improperly, it is easy to form a stalemate prematurely, affecting the fruit's commercial nature.
The third and fourth ear empty ear
The author once saw that the vegetables and tomatoes grown by a vegetable farmer were very tall and had crossed the steel wire and were thin. It turned out that he had retained 9 panicles. He explained his behavior in this way: “In the past, my tomato was left with 5–6 spikes, but this year, the number of tomatoes in the third and fourth ear was very high. In order to ensure yield, there was no way to leave 9 spikes. The output still did not reach the previous 5-6 spikes.†Through the exchange, the author learned that the main cause of empty ears of tomatoes is insufficient nutrient supply.
(1) Too much fruit in the lower ear. In the early stages of fruit set in the tomatoes, due to the high temperature at that time, the plants were susceptible to growth, many vegetable farmers were afraid to sit still, taking the practice of keeping more fruit trees, and some vegetable farmers first fruits 5-6, resulting in falling serious.
(2) In the event that the weather is too hot, the fertilizer is not timely or the leaves are too heavy, the nutrient is insufficient and the flower buds are poorly differentiated, resulting in more empty-spike phenomenon.
The main reasons for the hollow fruit in the upper part of the ear are more hollow fruit in the upper part of the ear:
(1) When the upper fruit of the tomato enters the fruit-expanding stage, it is in the low-temperature, widow-lit season after entering the winter. To promote the transformation of the lower fruit, many vegetable farmers pick up the leaves excessively. In addition, photosynthetic capacity decreased, photosynthetic products decreased, nutrients that supply fruit growth were insufficient, and hollow fruit occurred more often because of poor nutrition supply or disease such as leaf mold in the late growth stage.
(2) The watering and fertilization in the later period is reduced. Many vegetable farmers stop watering and fertilizing tomatoes and three panicles when they are immature. The nutrients and water in the soil cannot meet the needs of tomato fruit growth, and the growth of pulp is affected, resulting in empty fruit.
solution
In order to ensure more quality fruit and prevent problems such as stale fruit, empty ear, and hollow fruit, in addition to cultivating strong trees and increasing plant resistance, we specifically remind farmers to pay attention to the following points:
(1) Remove the first flower of each spike flower, spend more flowers, early fruit thinning, and leave good fruit.
Since the first flower of each spike flower is open early, it is prone to malformation after sitting and holding fruit, it will also affect the nutritional supply of other flowers, and it will seriously lead to falling flowers and dead fruits. Therefore, it should be promptly removed. Each flower can spend 6-8 flowers, when the tomato grows to the size of the pigeon egg, remove the deformed, injured and too large and small fruit, fruit 3 to 5 per ear.
(2) Control points spent time and dosage.
If you spend time improperly, it is easy to form a stalemate too early, and it is easy to form a crack if it is too late, which will affect the commodity. The flower on each ear starts from the second flower, and basically every time it is 2 - 3 flowers open on the same day. At this time, it starts to spend, preferably when the flowers are just open in the morning. For point anther concentrations, the preparation concentration should be slightly higher at low temperatures and slightly lower at high temperatures.
(3) The fertilizer and water in the fruit expansion period must keep up. (4) The leaves should not be excessive in the later period.
In the fruit coloring period, many vegetable farmers to promote fruit color conversion, increase light, not only the entire lower part of the removal of the leaves of the ear, the upper leaves are also removed a lot, too few leaves, seriously affecting the photosynthetic accumulation of leaves, nutritional deficiencies, Cause hollow fruit and other issues. Therefore, snoring and picking leaves in the middle and late stages of growth are appropriate and should not be excessive.
