Post-use management of plant growth regulators

Plant growth regulators are widely used in China. Rational use is very beneficial to the growth of crops, can ensure its yield and quality, and effectively improve the planting efficiency of growers. However, after we use plant growth regulators, we need to do a good job of management. So how to manage plant growth regulators after use? Let's take a look at it with the editor.

1. Fertilizer and water management

After using plant growth regulators, the first thing we should do well is fertilizer and water management. Fertilization should be based on organic fertilizer, combined with appropriate amount of chemical fertilizer. When applying base fertilizer, it is necessary to ensure that it is adequate and rotten, and do a good job of topdressing. Attention should be paid not only to the application of nitrogen, phosphorus and potassium fertilizer, but also to the use of micro-fertilizer. After spraying, because the main purpose of plant growth regulators is to protect flowers and fruits and increase the rate of fruit setting. At this time, crops have a greater demand for water, so we should pay attention to watering, combined with fertilization. It should be noted that it should not be carried out at high temperature at noon to avoid water evaporation too quickly.

2. Tree potential management

Tree posture management is also very important, for example, for fruit trees, if the amount of fruit is too much, then it is necessary to timely thinning flowers and fruits. According to the tree potential to adjust the specific amount of removal, mainly disease and insect fruit, overdense growth and abnormal fruit. Then, we should pay attention to control the growth of the summer shoot, and we can pick the heart of the new shoot to avoid the summer shoot growing too fast, resulting in all the plant growth regulators acting on the summer shoot. Promote the reproductive growth of fruit trees, so as to improve the effect of plant growth regulators, and achieve the purpose of increasing production and income.

Then it is necessary to do a good job of pruning, proper pruning can avoid too dense growth between branches, too much shade, affecting growth, so as to improve crop photosynthesis and maximize the effect of plant growth regulators. Pruning should usually be carried out after fruit harvest or after thinning flowers and fruits. The pruning objects are mainly weak branches, withered branches and over-long and over-dense branches to prevent the branches from grabbing nutrition and ensure that the fruit can expand normally.

3. Pest control

Pest control is also our management focus after the use of plant growth regulators. Attention should be paid to the prevention and control period, according to the law of the development of diseases and insect pests, timely drug control, from the root causes to reduce the harm of diseases and insect pests. Then when choosing pesticides, we should give priority to those with low toxicity and high efficiency. According to the instructions, strictly control the concentration of pesticides, not too large. At the same time, be careful not to use insecticides during flowering, and not to spray pesticides in the high temperature and rainy season. At the same time, we should also pay attention to the sensitivity of crops to pesticides to avoid drug damage.

The above is a brief introduction to the management after the use of plant growth regulators. That's all for today's introduction. This article is for reference only. I hope it can help you all.
