Embodiment

[0017] Embodiment: Spinach test

[0018] 1 Experimental design

[0019] Vegetables used in the test were Thai Shuangaxe spinach varieties. There are 4 treatments in the experiment, namely: treatment 1-no fertilization (CK1); treatment 2-application of special fertilizer for common vegetables (CK2, the application rate of each component is: N12kg / mu; P 2 o 5 4.8kg / mu; K 2 (06.0kg / mu, i.e. monoammonium phosphate 9.6kg / mu, potassium chloride 10kg / mu, urea 24kg / mu); process 3-use special fertilizer A for inorganic type vegetables of the present invention (WFS-A, each component applies Dosage: N12kg / mu, P 2 o 5 4.8kg / mu, K 2 (06.0kg / mu, i.e. monoammonium phosphate 9.6kg / mu, potassium chloride 10kg / mu, urea 24kg / mu; sodium polyacrylate 2kg / mu, polyacrylamide 2kg / mu); process 4-apply the inorganic Vegetable special fertilizer B (WFS-B, the application rate of each component is: N12kg / mu; P 2 o 5 4.8kg / mu; K 2 O6.0kg / mu, that is, monoammonium phosphate 9.6kg / mu, potassium...

Abstract

The invention discloses an inorganic special vegetable fertilizer with the functions of moisture and fertilizer retention and soil reinforcement. The inorganic special fertilizer is prepared from N, P2O5, K2O, super absorbent resins and high polymers according to the weight ratio of 12:4.8:6:2:2 according to the requirement of vegetable growth in soil loss regions in southern China on fertilizers. The prepared inorganic special vegetable fertilizer can achieve the effects of effectively improving the water and fertilizer use efficiency, alleviating the labor intensity, saving labor employment, increasing labor benefits and reducing water and soil loss, is expected to improve the yield and quality of vegetables and has realistic significance of promoting income growth of the peasants, growth of agricultural efficiency, rural development and environmental protection of agriculture ecology.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizers, and in particular relates to an inorganic-type special fertilizer for vegetables, which has the functions of water and fertilizer conservation and soil fixation. Background technique [0002] According to the latest report of the Ministry of Water Resources of China, the soil erosion area in my country has reached 3.5692 million km 2 , the area to be treated urgently is nearly 2 million km 2 . Especially in the red soil area in southern my country, due to the large amount of rainfall and concentration, the low mountains and hills intersect, the terrain is broken, the slope is large, the parent rock has weak corrosion resistance, and the developed red soil is highly erodible. In addition, the population density is large, and the contradiction between man and land is prominent. , is one of the areas with the most severe soil erosion in my country. At present, the harms of soil erosio...
