The reason why tomatoes are not big is why

I. Varieties: There is little difference in the size of each fruit in some varieties. These varieties are suitable for long-term harvesting, and the results can reach 17, 18 or even 20 fruits. Generally, these seeds are more expensive. Another common and popular variety, each fruit is smaller than the previous one, that is, the smaller the fruit is. These varieties are suitable for cultivation in a shorter harvest period. Generally, 3 to 4 sets of fruit are knotted. After that, the head must be steamed, and generally 3 to 4 fruits per ear.

Second, the fertilizer: the lack of all kinds of essential elements of the plant will cause the fruit to become smaller, the lack of magnesium, manganese, boron may affect the size of the fruit. In addition, the improper application of fertilizers will also affect the size of the fruit. For example, if a large amount of ruminant feces is applied and no large amount of nitrogen is applied, the crop will be deficient in nitrogen. Excessive and frequent application of large amounts of diammonium causes phosphorus poisoning in crops and the fruit will become smaller. The correct application method of potassium fertilizer is to apply in several stages. If it is put in one time, the crop will be reduced, and the same amount will be divided into three times (the first time is less), and the yield increase is large. Excessive amounts of some elements, such as boron spray, can also make the fruit smaller. Linyi Fertilizer Network Copyright

Third, cultivation aspects: 1. No frame, plant lodging; 2. The latter type of species did not go head; 3. Water shortage; 4. Soil over stiff; 5. Auxin poisoning - this is the most common fruit in the greenhouse The reason for the smaller (one layer of flowers per point, the auxin accumulates a little, the fruit after three or four sets of fruit is affected), should be corrected once every three to four after gibberellin.
