Disease-preventive selenium-rich organic compound fertilizer for grape planting and preparation method thereof

Abstract

The invention provides a disease-preventive selenium-rich organic compound fertilizer for grape planting and a preparation method thereof. The compound fertilizer comprises the following components in parts by weight: urea, an organic fertilizer, ammonium dihydrogen phosphate, mono-ammonium phosphate, potassium chloride, zinc sulfate, humic acid, attapulgite, bacillus subtilis, sodium selenite, EDTA (ethylene diamine tetraacetic acid) chelated iron, EDTA chelated zinc, EDTA chelated copper, amino acid chelated manganese, amino acid chelated iron, amino acid chelated molybdenum, a urease inhibitor, a nitrification inhibitor, and paclobutrazol. The compound fertilizer is an organic-inorganic compound mixed fertilizer, is long in fertilizer effect, can cover the grape planting period by single-dose application, does not need to be replaced, is rich in multiple trace elements, can increase the types and contents of nutrient elements in soil and promote the nutritive values of grapes, contains microbial strains combined with a bactericide to promote the disease resistance of the grapes during planting, is low in production cost, is beneficial for market popularization, and is good in economic benefit.

Description

technical field [0001] The invention relates to a disease-proof and selenium-enriched organic compound fertilizer for grape planting and a preparation method thereof. Background technique [0002] Grape (English name: grape, scientific name: VitisviniferaL.) Vitiaceae Vitis woody vine, branchlets cylindrical, longitudinally ribbed, glabrous or sparsely pubescent, oval leaves, dense or scattered panicles, many flowers , Opposite the leaves, the base branch is developed, the fruit is spherical or oval, the seeds are obovate-oval, the flowering period is April-May, and the fruiting period is August-September. [0003] Similar to most crops, grapes need about 17 nutrients for their growth: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, chlorine , drill, the carbon and oxygen in the base are carbon dioxide from the air during photosynthesis, and the hydrogen comes from the water in the soil...

AI Technical Summary

Problems solved by technology

However, the fertilizer provided by this patent is dedicated to the base fertilizer, which means that other fertilizers will be applied later to meet the growth needs of grape planting. Too many types of fertilizers will affect the soil quality, and its trace elements exist in the form of sulfate. Difficulty absorbing
