High-organic-matter-fertilizer evaporation-and-transpiration-reducing water-saving method and application of evaporation-and-transpiration-reducing water-saving method to planting saline-and-alkaline-land photinia serrulata

Abstract

The invention relates to a high-organic-matter-fertilizer evaporation-and-transpiration-reducing water-saving method. The high-organic-matter-fertilizer evaporation-and-transpiration-reducing water-saving method includes the steps of film covering; drip irrigation system laying; drip irrigation conducting, wherein post-planting-surviving drip irrigation is carried out, water-and-fertility mixing liquid containing high-organic-matter fertilizer is subjected to drip irrigation once every 60 days. The high-organic-matter fertilizer is prepared from, by weight, 23-25 parts of ammonium sulfate, 20-22 parts of ammonium superphosphate, 19-21 parts of potassium chloride, 18-20 parts of boric acid, 7-9 parts of chelated copper, 7-9 parts of manganese sulfate, 5-7 parts of zinc sulphate monohydrate, 4-6 parts of chelated iron, 1-3 parts of polypeptide, 1-3 parts of potassium fulvic acid, 1-3 parts of alginic acid, 1-3 parts of humic acid, 0.1-0.3 part of silybum marianum extract, 0.1-0.3 part of chlormequat chloride, 0.1-0.3 part of thiophanate methyl, 0.1-0.3 part of chlorothalonil, 0.1-0.3 part of indolebutyric acid, 0.1-0.3 part of 6-benzyl aminopurine, 1-3 parts of polyaspartic acid and 1-3 parts of acetamide.

Description

technical field [0001] The invention relates to a method for reducing steam and saving water by using high-organic-matter fertilizers, in particular to a method for reducing steam and saving water by using high-organic-matter fertilizers and its application in planting Photinia fruticosa in saline-alkali land, belonging to the technical field of agricultural planting. Background technique [0002] Photinia is the collective name for the hybrid species of Photinia in the family Rosaceae. It is an evergreen small tree with a plant height of 4-6 meters. The leaves are leathery, oblong to obovate-lanceolate, and the new leaves are red in spring and turn green in summer. Autumn, winter, spring The three seasons are red, the color of frost is thicker, and the color of low temperature is better. As a street tree, its pole stands like a torch; as a hedge, its shape lies like a fire dragon; with pruning and landscaping, its shape can be in various poses and with different expressions...

AI Technical Summary

Problems solved by technology

[0004] Planting plants on saline-alkali land, the soil porosity of the saline-alkali land is relatively large, and the conventional flood irrigation method is likely to cause a large amount of water leakage in the deep soil layer, resulting in a low moisture content in the soil layer; at the same time, the fresh water on the saline-alkali land is relatively scarce, The utilization rate of water is low. In order to meet the water required for plant growth, a large amount of fresh water is required for irrigation, and transpiration and evaporation will also take away a large amount of water, resulting in a low water utilization rate.
