Evaporation reducing water-saving method using iron-containing fertilizer and application thereof in planting saline-alkali soil oleander

Abstract

The invention relates to an evaporation reducing water-saving method using iron-containing fertilizer. The method comprises: laying a sprinkling irrigation system and performing sprinkling irrigation. Sprinkling irrigation includes sprinkling irrigation in a seedling stage, sprinkling irrigation in a growing period, and sprinkling irrigation in a cutting stage. The sprinkling irrigation in a growing period uses a mixed sprinkling irrigation method of using iron-containing fertilizer salt water and fresh water. The iron-containing fertilizer contains components in the following parts by weight: 21-23 parts of monoammonium phosphate, 15-17 parts of monopotassium phosphate, 10-13 parts of ammonium bicarbonate, 8-10 parts of ammonium phosphate, 5-7 parts of ammonium chloride, 3-5 parts of Fe-chelate, 2-4 parts of grape vinegar, 1-3 parts of fulvic acid potassium, 0.2-0.4 parts of silybum marianum extract, 0.1-0.3 parts of simazine, 0.1-0.3 parts of paclobutrazol, 0.1-0.3 parts of chlorothalonil, 0.1-0.3 parts of fenaminosulf, 1-3 parts of 5-nitroguaiacol sodium salt, 1-3 parts of urethane, and 50-52 parts of water.

Description

technical field [0001] The invention relates to a method for reducing steam and saving water by using iron-containing fertilizers, in particular to a method for reducing steam and saving water by using iron-containing fertilizers and its application in planting ryegrass in saline-alkali land, belonging to the technical field of agricultural planting. Background technique [0002] Ryegrass is a perennial plant with 30-90 cm high culm and soft roots on the basal nodes. Liga ca. 2 mm; blade soft, hairy, sometimes with auricles. Spike-shaped spikes erect or slightly curved; coblets smooth and glabrous; glumes lanceolate, margin narrowly membranous; lemma oblong, herbaceous, smooth, without awn at the top; two ridges with short ciliates. Caryopsis about 3 times as long as wide. The flowering and fruiting period is from May to July. Excellent forage grasses that are widely introduced and cultivated in various places. Born in meadows, common in roadside wetlands. Widely distri...

AI Technical Summary

Problems solved by technology

[0003] 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. More losses through evaporation;

[0004] 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
