CN-122004101-A - Method for improving yield and quality of ginger

Abstract

The invention provides a method for improving yield and quality of ginger, and belongs to the technical field of ginger planting. The method for improving the yield and the quality of the ginger comprises the following steps of spraying a choline chloride aqueous solution on leaf surfaces for the first time in a growth vigorous period of ginger seedlings, wherein the concentration of choline chloride in the choline chloride aqueous solution is 75-350 mg/L. The method provided by the invention not only can promote the growth of ginger, but also can simultaneously improve the yield and quality of ginger, delay plant aging and prolong the harvesting period. In addition, the method provided by the invention has the advantages of environment friendliness, pollution reduction, improvement of soil ecology, protection of beneficial microorganisms, low cost and easiness in popularization.

Description

Method for improving yield and quality of ginger Technical Field The invention belongs to the technical field of ginger planting, and particularly relates to a method for improving ginger yield and quality. Background Ginger is used as an economic crop, the yield and quality improvement of the ginger is significant to the agricultural synergy and the income increase of farmers, however, the ginger industry faces the problems of prominent continuous cropping obstacle, single ginger variety, frequent soil-borne diseases and the like, and the yield and the quality are further affected. Common diseases of ginger mainly include ginger blast disease, bacterial wilt, basal rot, leaf spot, anthracnose and the like. The insect pest mainly comprises ginger maggots, nematodes and the like. In the ginger production management process, farmers often adopt modes of spraying pesticides in fields, sterilizing soil and the like to prevent and control diseases and insect pests, in order to pursue high yield, the phenomenon of blindly and excessively applying fertilizers is common, soil acidification, hardening and salinization are caused, beneficial microorganisms are killed due to abuse of pesticides, the balance of a soil ecosystem is destroyed, meanwhile, pesticide residues in the soil are easily caused, the soil ecological environment is polluted, the yield of the ginger is further inhibited, and the commodity quality is reduced. Meanwhile, the ginger is long in growth period, and plants are easy to be presenilized in the later growth period. In addition, the winter vegetables have higher prices, so that how to improve the yield and quality of the ginger, delay the maturation, prolong the harvesting period of the ginger, realize green, high-quality, high-efficiency and sustainable production of the ginger, and have important application value for improving quality and efficiency and developing high quality of the ginger industry. In recent years, many studies have demonstrated that exogenous substances have a significant effect on quality and quality of crops, and plant growth regulators have been used in many crops, such as tomatoes, potatoes, sugarcane, wheat and the like, but have been relatively scarce in the search for a characteristic crop of ginger. The research and application of the plant growth regulator on ginger are enhanced, and the plant growth regulator has important value for promoting the quality improvement and the efficiency enhancement of the ginger industry. Disclosure of Invention Accordingly, the present invention is directed to a method for improving the yield and quality of ginger, which is of great value to the ginger industry and its development. In order to achieve the above object, the present invention provides the following technical solutions: The invention provides a method for improving ginger yield and quality, which comprises the following steps of spraying a choline chloride aqueous solution on leaves for the first time in a growth vigorous period of ginger seedlings, wherein the concentration of choline chloride in the choline chloride aqueous solution is 75-350 mg/L. Preferably, after the first spraying, spraying the choline chloride aqueous solution on the leaf surfaces for the second time at intervals of 13-15 days. Preferably, the vigorous growth period is a period after the main stem is provided with 4 branches at both sides to form 5 seedlings. Preferably, spraying is performed at 7:00-10:00 am or at 16:00-18:00 pm. Preferably, the spray is applied to all of the front and back sides of the blade to be wet, but the droplets do not polymerize and fall to the extent. Preferably, the ginger is Dioscorea zingiberensis. Preferably, the total number of spraying of the aqueous choline chloride solution is 2. Preferably, improving ginger quality includes reducing lignin content, increasing vitamin C content, reducing gingerol content, and/or reducing crude fiber content. The invention has the beneficial effects that: The method provided by the invention not only can promote the growth of ginger, but also can simultaneously improve the yield and quality of ginger, delay plant aging and prolong the harvesting period. In addition, the method provided by the invention has the advantages of environment friendliness, pollution reduction, improvement of soil ecology, protection of beneficial microorganisms, low cost and easiness in popularization.
