Zinc-sulfur nitrogen fertilizer

Abstract

The invention discloses a zinc-sulfur nitrogen fertilizer, and relates to the technical field of fertilizer formulas. The zinc-sulfur nitrogen fertilizer is prepared from, by weight, 55 parts of ammonium sulfate, 0.8 part of zinc, 0.3 part of boron, 0.6 part of silicon, 18 parts of nitrogen, 5 parts of polyaspartic acid, 6 parts of DA-6 triacontanol, 12 parts of plant ash, 11 parts of canal mud, 10 parts of rape seed cake, 25 parts of bentonite, 1 part of lemon and 1 part of radix rubiae. The fertilizer is simple in formula and convenient to prepare in combination with organic fertilizer; besides, the formula includes zinc, nitrogen and other microelements, and thus the fertilizer can increase yield, resist diseases, improve soil, prevent soil from hardening, effectively increase the zinc content of soil and promote the zinc absorption of plants; moreover, due to the reasonable ingredient proportion, the zinc absorption rate of plants is high; by adding lemon and radix rubiae in the fertilizer, the zinc absorption of crops can be further improved, the zinc content of fruits can be greatly increased, and crops are higher in nutritional value and more significant in economic benefit.

Description

[0001] Technical field: [0002] The invention relates to a zinc-sulfur-nitrogen fertilizer and belongs to the technical field of fertilizer formula. [0003] Background technique: [0004] There are zinc deficiency problems in many arable land soils around the world, so various crops are often prone to mild zinc deficiency. The role of zinc in plants mainly includes: 1. One of the essential elements for plant growth and development; 2. The constituent elements of certain enzymes in plants; 3. It is an element necessary to promote some metabolic reactions; 4. It is essential for chlorophyll production and carbohydrate formation Elements. Zinc deficiency in fruit trees can be seen in both the north and the south of my country. It often manifests as leaf chlorosis, and small leaves and clusters appear on the tips of branches, that is, "small leaf disease". When zinc deficiency is severe, the branches die and the yield decreases. Zinc deficiency is more common in apple and peach...

Problems solved by technology

At present, most of the existing zinc fertilizers are foliar spraying, and the effect of foliar fertilization is limited for a short period of time. Usually, it takes more than two times to be effective, and it is affected by the weather, spraying concentration, spraying location, etc.

With increasing labor costs, incremental revenue may not be sufficient to cover the cost of spraying
