Fruit retention is a very critical task in tomato management. If there are less fruits, the trees will prosper, without or less fruit. If there are too many fruits, the trees will fall and empty fruit or empty ears will occur. Many vegetable farmers reported that the first fruit of the tomato grows well and big, but the second fruit of the tomato is not swelling. Some vegetable farmers report that the tomato has a six or seven ear fruit. The longer the plant, the thinner and yellow head. ; There are also vegetable farmers who report that when the crop is about to change every year, the tomatoes have not grown enough... Then, how do tomatoes retain fruit?
The general principle is: more flowers, early fruit thinning; less fruit, good fruit; 3-5 fruit per ear is appropriate.
Determine the number of ears to stay according to the crop
The extension of autumn tomatoes is generally planted at the end of July and early August, and the seedlings are planted in the middle and late December and then planted in spring. In this crop of tomatoes, six or seven panicles are generally reserved for the beginning, except for the first panicle, there are 4-5 per panicle. Many vegetable farmers change stubble late, such as planting in early September, but want to change seedlings in mid-to-late December. In this case, the number of ears should be appropriately reduced, leaving only 4 ears of fruit. In order to reduce losses, the number of retained fruits can be increased appropriately. Generally, 4 for the first ear and 5-6 for the others. Due to the small number of remaining fruit ears and relatively sufficient nutrient supply, premature senescence generally does not occur.
Decide how much fruit to keep based on growth
In the case of normal plant growth, the first ear fruit often has sufficient nutrient supply and the fruit grows larger. If too much fruit is retained, it is easy to fall on the tree and affect the upper fruit setting. It is advisable to leave 3 fruit. From the second ear to the fifth ear, there are 4 fruits each, so that the lower fruits can grow normally without affecting the growth of the upper fruits. You can leave 5 for the sixth and seventh panicle, because when the lower fruit is picked, the sixth and seventh panicle is in the puffing period, so as the number of tomatoes on the tree decreases, the nutrients produced by the leaves can fully satisfy the sixth and seventh panicle. The growth needs. If the plants are growing too vigorously at the early stage of fruiting, you can also save 4 first ear fruits to fall into the trees to avoid excessive plant growth and affect the upper flowering and fruit setting. Look at the growth of the second ear fruit and leave 3-4. When the plant grows poorly, because its nutrient accumulation is insufficient, it is difficult to meet the normal development of flowers and fruits, so the flower and fruit retention should be light and less. The first ear fruit should be reduced or not retained. If the growth of the plant is weak, it is recommended that the vegetable grower remove the first flower, promote the growth of the plant first, cultivate strong trees, and then plant flowers and retain fruits.
