Special paste foliar fertilizer additive containing wood-vinegar base insecticidal synergist and applied to pears

Abstract

The invention discloses a special paste foliar fertilizer additive containing a wood-vinegar base insecticidal synergist and applied to pears. First, crude pure wood vinegar is refined and mixed with lignin to enhance the viscosity of the wood vinegar, and then benzaldehyde L-cysteine Schiff base formed from the reaction of benzaldehyde and L-cysteine is added to the wood vinegar. The insecticidal synergist has a good inhibitory effect on phenol oxidase in pest bodies and has a good insecticidal effect; at the same time, as the wood vinegar can delay the infection period of pests, and the special smell of the wood vinegar can expel the pests and can reduce the growth and reproduction capacity of the pests, the harm of pests to crops is reduced; after being added to paste foliar fertilizer, the product can enhance the fertilizer effect, has the insecticidal effect, is safe and non-toxic actually, is used for increasing yield of the pears and controlling the pest and disease damage and can realize the effect of combination of a pesticide and fertilizer, thereby having good application prospect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a paste-like foliar fertilizer additive for pear trees added with a wood vinegar base insecticidal synergist. Background technique [0002] Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts its basic function through the absorption of leaves. The pores on the surface of leaves are the channels for foliar fertilizer to enter the leaves. It has fast absorption, strong effect, low dosage and high efficiency. High characteristics can supplement the deficiency of root fertilization. During the growth process of crops, crops have shown some nutrient deficiency. Since it takes a certain time for soil fertilization, nutrients can be absorbed by crops, and the deficiency of crops cannot be alleviated in time. Symptoms, at this time, foliar fertilization can make nutrients quickly enter the plant through the leaves and solve the p...

Problems solved by technology

In the article, the foliar fertilizer adopts a liquid formula, which has low nutrient content and is easy to crystallize out, and it is easy to lose when applied to the foliage, resulting in waste of fertilizer. Paste fertilizer is a form between solid fertilizer and liquid fertilizer. With the increase of water volume, its fluidity increases, which overcomes the shortcomings of solid fertilizers, which are easy to absorb moisture and agglomerate, dissolve slowly during use, and liquid fertilizers have low nutrient content and are easy to crystallize and precipitate.
