Compound agent of high-resistance successive crop

Abstract

The invention relates to agricultural chemistry, in particular to a polypharmaceutical with high successive cropping resistance of crops, which is characterized in that the polypharmaceutical consists of 23 to 27 percent of nutrition enhancement balancer, 10 to 30 percent of plant growth regulator, and 20 to 25 percent of bactericide. Experiments prove that the successive cropping resistant capability of the crops can be improved by more than 90 percent after the use, and the grafting effect can be achieved; and the absorptivity of the crops to nutritive substances is improved to 97 percent, the crops are mature 8 days earlier, melon and vegetable crops are increased by between 30 and 80 percent in yield, and field crops are increased by between 30 and 50 percent in yield.

Description

technical field

[0001] The invention relates to agricultural chemistry, in particular to a compound drug highly resistant to repeated crop crops. Background technique

[0002] The method of planting the same crop in the same plot year after year is called continuous cropping or double cropping. Heavy crops generally have low survival rate, poor growth, low root activity, poor stress resistance, few fibrous roots, few fruits, low yield, poor quality and short life span. This phenomenon is called the problem of repeated cropping in my country, the phenomenon of taboo in Japan, and the problem of replanting or replanting disease in European and American countries. Studies have found that generally watermelon can only be planted again after 7-8 years of crop rotation, otherwise it is easy to cause a large number of seedlings to die or even fail due to the occurrence of Fusarium wilt; strawberry cropping for 4 years can reduce the yield by more than 40%. The disease of repeated...

[0008] The method of use and the scope of application of the agent: it can be used for all crops, and the benefits are high for melons, vegetables and economic crops. It is not limited by climatic conditions and can be used in all seasons. The dosage of pesticides has nothing to do with soil fertility. Regardless of the level of soil fertility, the dosage of pesticides is fixed. Generally, it is only used once during the growth period of crops, 50-65 ml per mu for melon crops, 50-60 ml per mu for beans, peanuts, potatoes, sugar beets, etc., 30-40 ml per mu for food crops, and 60-70 ml per mu for fruit trees. Milliliters, melon vegetables, tobacco, rice seedbeds are used in small amounts, and the effect is good. Adding 90 kg of water to 10 milliliters of medicine can use 1.5 minutes of seedbed, and 10 milliliters of fruit trees can use 1 minute of seedbed. The medicament is a soil application product, and the method of use is simple. It can be used to mix seeds and fertilizers,...
