A specific medicine for protecting flowers and fruits

The specific drugs for flower and fruit protection are rutin, sodium naphthalene acetate, gibberellin, cytokinin, sodium nitrophenol, zinc benzoate, thiram and so on, but gibberellin and cytokinin are often used now. it is generally suggested that it can be used together with boron-calcium foliar fertilizer after 2 / 3 flower shedding, and the effect will be better. Of course, in terms of enhancing crop resistance to stress, timely fertilization and prevention of diseases and insect pests can also protect flowers and fruits.

In addition to the above introduction, the following methods can also protect flowers and fruits:

1. Do a good job in the use of nutrient elements in fruit trees and the use of element fertilizer. Adequate supply of fertilizer is a necessary condition for fruit tree growth, flowering and fruiting. Nutrient elements such as phosphorus, potassium, calcium, boron and zinc are closely related to flowering and fruiting. Phosphorus is the energy element of cell division. Potassium is the quality element to improve stress resistance and quality. Calcium is the main component of cell wall and the key element to enhance fruit resistance. Boron and zinc can be said to be the reproductive elements of fruit trees. It can ensure the normal growth and development of reproductive organs.

In addition to the daily use of nitrogen, phosphorus and potassium fertilizer, it must be used with element foliar fertilizer containing enzyme power, which can activate and promote the absorption of nitrogen, phosphorus, potassium, boron, calcium, zinc, molybdenum and other elements in fruit trees. in particular, the enzyme-powered foliar fertilizer containing boron, calcium and molybdenum elements, but also strengthened the plant flower and fruit protection and later fruit tree nutrition demand, this good use of fruit trees to protect flowers and fruits play a very good role.

2. Pest control is in place, pay attention to the combination of prevention and control, prevention-oriented, rational use of pesticides.

3. Pay attention to controlling the vegetative growth of fruit trees, such as preventing the branches of fruit trees from flourishing, regulating the contradiction between vegetative growth and flowering and fruiting, and promoting fruit trees to go all out to ensure normal reproductive growth.

4. If due to climate change, such as frost, late spring cold, etc., fruit trees have poor flower bud differentiation or serious flower and fruit drop after flowering, some regulators can be used to regulate and control. Generally speaking, gibberellins and cytokinins are used to protect fruit, and it is generally recommended to protect fruit after 2 / 3 of flowers. When using fruit-preserving drugs, it is suggested that the effect of using boron-calcium foliar fertilizer together with boron-calcium foliar fertilizer will be better, because the foliar fertilizer supplemented with calcium and boron can absorb and transform boron and calcium better, and for some varieties that are difficult to protect fruit, it can also be used again after half a month, but it should be stated that the dosage of regulators must be controlled and should not be used too frequently.

The above is the introduction of the specific medicine for flower and fruit protection. I hope it will be helpful to everyone.
