How to Control Excessive Growth of Tomatoes?
The overgrowth will occur at seedling stage and adult stage. The seedling stage is characterized by slender stems, long internodes and light green leaves. At the mature stage, the plants are flourishing with many leaves, but with few fruit and low yield. Lack of sunshine, too much fertilization, especially large amount of ammonium nitrogen fertilizer and high soil moisture are prone to excessive growth, which leads to delayed flowering and fruiting. Small difference in temperature between day and night can easily lead to overgrowth of plants.1. Control fertilizer and water.
In general, there is enough basal fertilizer water, so it is not necessary to apply fertilizer water before flowering and fruiting of tomatoes. Spraying Zhuangti Fertilizer in time before flowering in young fruit stage and expansion stage can activate the positive energy of plant ecological growth, broaden the path of plant conduit, improve the absorption of water and fertility of plants, improve the yield and quality of fruits, reduce the rate of falling fruits and the incidence of cracked fruits, stiff fruits and deformed fruits.
2. Strictly control the seedling age and plant it in time.
For example, the seedling age of general early-maturing tomato varieties is about 60 days, that of middle-late-maturing tomato varieties is about 70-80 days, and that of autumn tomato is about 25 days.
3. Pruning and lopping.
Pruning and lopping in proper amount, setting up a frame, making good ventilation, spraying flowers with growth regulators such as anti-falling spray, promoting fruiting and inhibiting excessive nutrient in growth.
4. Application of chemicals.
After planting seedlings, spraying a new high-fat film to form a polymer film every 15 days or so, can keep plants warm and moisture to prevent pathogen infection. Spraying Cuhuawang No.3 in time during the flower bud differentiation period can promote the transmembrane signal conversion of plant cells by assimilation induction, force the vigorous nutrition of the top tips to flow back in large quantities, and quickly weaken the inertia advantage of the top tips to the capping. The main nutrition of its trunk turns to the young fruit cultivation system, which promotes the fruit expansion vitality, avoids the leaf hypertrophy and improves the field permeability.
