Special fertilizer for low temperature planting of water convolvulus

Abstract

The invention discloses a special fertilizer for low temperature planting of water convolvulus. The special fertilizer is prepared from urea, ammonium nitrate, monopotassium phosphate, potassium sulphate, potassium fulvic acid, calcium nitrate, magnesium sulfate, borax, zinc sulfate, ferrous sulfate, copper sulfate, a microorganism bacterium agent, a growth regulating agent, a rare earth micro-fertilizer and an additive. According to the special fertilizer, the microorganism bacterium agent and the growth regulating agent both have the effects of increasing the photosynthesis rate of the water convolvulus and promoting nutrient substance absorption and can improve the soil environment and decrease the crop morbidity; the growth regulating agent, the additive and the inorganic fertilizer can effectively reduce cytosol exudation, conserve water and enhance the plant capacity for repairing a cellular membrane system in time and the freeze injury preventing capacity through cooperative usage. The normal vital movement of the water convolvulus in a low temperature environment is guaranteed by promoting the photosynthesis rate of the water convolvulus and improving the freeze injury preventing capacity of the water convolvulus, and the very good promoting effect on planting and popularizing of the water convolvulus in low temperature regions is achieved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special fertilizer for low-temperature planting of water spinach. Background technique [0002] Water spinach (Ipomoea aquatica), formerly known as Yongcai, also known as rattan vegetable, water spinach, spinach, macaroni, Chinese cabbage, urn vegetable, empty tube vegetable, bamboo leaf vegetable, is an annual or perennial vine herbaceous plant in the family Convolvulaceae. It is native to tropical and rainy regions of my country and is suitable for growing in humid regions. It is mainly distributed in Lingnan region and is a green leafy vegetable commonly cultivated in summer and autumn in southern China. It has white trumpet-shaped flowers and is called "water spinach" because the center of the stalk is hollow. [0003] Water spinach naturally likes a high temperature and high humidity environment, and generally grows in seasons and regions above 20°C. When the temperature drops, the photo...
