Key Management Points After Using Plant Growth Regulators

Plant growth regulators are used very widely in China. Rational use is very beneficial to crop growth, can ensure yield and quality, and effectively improve growers' planting returns. However, after we use plant growth regulators, we need to do a good job of management. So how should management be carried out after using plant growth regulators? Let's take a look together below!

1. Fertilizer and Water Management

After using plant growth regulators, the first thing we need to do well is fertilizer and water management. Fertilization should be mainly organic fertilizer, combined with an appropriate amount of chemical fertilizer. When applying base fertilizer, it must be sufficient and fully decomposed, and topdressing should also be done well. Among these, attention should be paid not only to the application of nitrogen, phosphorus and potassium fertilizers, but also to the use of micro-fertilizers. After spraying, because plant growth regulators are mainly aimed at preserving flowers and fruits and increasing the fruit-setting rate, crops have a relatively large demand for water at this time, so attention should be paid to watering, combined with fertilization. Note that it should not be done at noon during high temperatures, to avoid excessive water evaporation.

2. Tree Vigor Management

Tree vigor management is also very important. For example, for fruit trees, if the fruit load is too heavy, then flower and fruit thinning should be carried out in time. Adjust the specific thinning amount according to the tree vigor, mainly focusing on diseased and insect-damaged fruits, overly densely growing fruits and deformed fruits. Then attention should be paid to controlling the growth of summer shoots. The new shoots can be pinched off to prevent the summer shoots from growing too fast, which would cause all the plant growth regulators to act on the summer shoots. This promotes the reproductive growth of fruit trees, thereby improving the effect of plant growth regulators and achieving the goal of increasing yield and income.

Then pruning work should also be done well. Proper pruning can prevent branches from growing too densely with each other and excessive shading, which affects growth, thereby improving the crop's photosynthesis and ensuring the maximum effect of plant growth regulators. Pruning work should usually be carried out after fruit harvest or after flower and fruit thinning. The targets of pruning are mainly weak branches, dead branches and overly long and dense branches, to prevent branches from competing for nutrients and ensure that fruits can expand normally.

3. Pest and Disease Control

Pest and disease control is also a key point of management after we use plant growth regulators. Attention should be paid to the control period, and according to the development patterns of pests and diseases, pesticides should be applied in time for control, reducing the harm of pests and diseases from the root. Then when choosing pesticides, low-toxicity and high-efficiency ones should be mainly used. Strictly control the concentration preparation of pesticides according to the instructions, and it must not be too high. At the same time, during the flowering period, attention should be paid not to use insecticides, and pesticides should not be sprayed during high-temperature rainy seasons. Attention should also be paid to the sensitivity of crops to pesticides to avoid phytotoxicity.

The above is a brief introduction to management after using plant growth regulators. That's all for today's introduction. This article is for reference only, and we hope it can help everyone!
