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...

2. Deficiency or imbalance of nutrient elements: Continuous planting of certain crops in the same soil consumes some nutrient elements one-sidedly, which makes the soil nutrient elements appear physiologically unbalanced, and some elements such as Fe, Mn, B, and Zn continue to decrease, resulting in Crop nutrient balance is out of balance, leading to deficiencies

3. Self-poisoning phenomenon: Self-poisoning phenomenon means that during the decay and decomposition process of the residues of previous crops, some toxins will be produced, such as organic acids, aldehydes, alcohols, and hydrocarbons, which have a significant inhibitory effect on the next crops, affecting the growth of the crop itself

If this micro-ecological environment is destroyed, for many cropping crops, even if the disease is prevented, the insects are cured, and the fertilizer is applied, the problem of the cropping disease cannot be completely solved.
