Problems solved by technology

The large yield and high income of sweet potato have prompted the market to blindly expand production. Due to the lack of planting technology and experience, sweet potato has been cropped continuously for many years, resulting in nutrient imbalance in the soil, lack of medium elements, and accumulation of sweet potato allelopathic and autotoxic substances and various pathogens in the soil. , Serious pest damage, abnormal climate, high temperature and drough

Abstract

The invention discloses a functional liquid fertilizer for promoting branching and tuberization of sweet potatoes. The functional liquid fertilizer comprises the following components in percentage byweight: 4-12% of a composite nematode-preventing microbial agent, 4-12% of a composite continuous cropping-resistant microbial agent, 5-20% of a macroelement fertilizer, 2-6% of a medium element fertilizer, 20-40% of active humic acid, 20-40% of an organic matter, 0.1-0.8% of a plant growth regulator, 0.5-3% of a surfactant and the balance of water. The functional liquid fertilizer can improve thesurvival rate of the sweet potatoes, promote early branching and more tuberization of the sweet potatoes, reduce continuous cropping hazards such as stem nematode disease and black spot of the sweetpotatoes, improve the tuberization rate and commodity rate of the sweet potatoes, and realize high quality and high yield of the sweet potatoes.

Description

Technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a functional liquid fertilizer for promoting the branching and setting of sweet potatoes and its application. Background technique [0002] my country is the world's largest producer of sweet potatoes. At present, my country's sweet potato planting area is about 65 million mu, ranking first in the world in terms of planting area and output, and ranking fourth in domestic food crop output, second only to rice, wheat and corn. The large yields and high profits of sweet potato urge the market to blindly expand production. The lack of planting technology and experience and the continuous cropping of sweet potatoes for many years have resulted in unbalanced nutrients in the soil, lack of medium elements, and accumulated sweet potato allelopathic autotoxins and various pathogens. , Severe pests and diseases, abnormal weather, high temperature and drought in summer, high rat...
