Evaporation-reducing water saving method adopting fertilizer containing gastrodin and application thereof in planting of saline-alkali soil alfalfa

Abstract

The invention relates to an evaporation-reducing water saving method adopting fertilizer containing gastrodin. The method comprises the following steps: laying a sprinkling irrigation system, and carrying out sprinkling irrigation, wherein sprinkling irrigation in a growth period adopts an irrigation manner that salt water containing gastrodin and fresh water are mixed, wherein the fertilizer containing gastrodin comprises the following components in parts by weight: 12-14 parts of ammonium nitrate, 10-12 parts of triple superphosphate, 8-10 parts of potassium sulphate, 8-10 parts of calcium chloride, 2-4 parts of chelated zinc, 1-3 parts of chelated copper, 1-3 parts of deacetylated chitin, 1-3 parts of polypeptide, 2-4 parts of potassium fulvate, 0.1-0.3 part of gastrodia elata extract, 0.2-0.4 part of sodium ortho-nitrophenol, 0.2-0.4 part of sodium salicylate, 1-3 parts of sodium naphthalene acetate, 0.1-0.3 part of thiourea, 0.1-0.3 part of polyoxin and 0.1-0.3 part of kasugamycin.

Description

technical field [0001] The invention relates to a method for reducing steam and saving water by using a fertilizer containing gastrodin, in particular, to a method for reducing steam and saving water by using a fertilizer containing gastrodin and its application in planting alfalfa in saline-alkali land, which belongs to agricultural planting technology field. Background technique [0002] Medicago sativa, formerly known as: Medicago sativa, also known as alfalfa, Latin name: Medicago sativa. Rosacea, Fabaceae, and Medicago are perennial herbs with strong roots that penetrate deep into the soil and have well-developed root necks. The stems are erect, clustered or even recumbent, quadrangular, glabrous or slightly pilose, with lush branches and leaves. Seeds ovate, 1-2.5mm long, smooth, yellow or brown. The flowering period is from May to July, and the fruiting period is from June to August. Native to Asia Minor, Iran, and Transcaucasus. It is cultivated or in a semi-wild...

AI Technical Summary

Problems solved by technology

[0004] The soil porosity in the saline-alkali land area is relatively large, the water for irrigation seeps down too quickly, and the moisture content of the soil layer is low. In addition, the fresh water in the saline-alkali land area is relatively scarce, and the amount of fresh water used is large, which cannot meet the growth needs of normal plants. There is more loss through evaporation; in addition, the survival rate of plants planted in saline-alkali land is low, the yield per mu of plants is low, and the nutrients contained in plants are low
