A method for cultivating kudzu tissue culture seedlings by using plant growth lamps

Abstract

The invention provides a method for cultivating pachyrhizua angulatus tissue culture seedlings by means of plant growth lamps. The method comprises the following steps of putting up a greenhouse, determining and customizing the plant growth lights, selecting a seedling-raising substrate, selecting pachyrhizua angulatus tissue culture seedlings, raising the seedlings and conducting seedling-raising management. The greenhouse adopts an ordinary steel frame structure, one side of the greenhouse is provided with a rolling gate used for being rolled up or laid down, and therefore the temperature in the greenhouse is adjusted; each plant growth lamp adopts an LED of which the lamp head power is 3 W, and a 220 v alternating current power supply is adopted to serve as a luminous source, wherein the ratio of red-light lamp heads to blue-light lamp heads is 7:2; the substrate is prepared from clean loess, yellow sand and organic fertilizer, the ratio of clean loess to yellow sand to organic fertilizer is 1 to 1 to 0.2, and the organic fertilizer is prepared by evenly blending and fermenting sheep manure, chicken manure, peanut bran and tea bran according to the proportion of 1:1:0.5:0.2. The survival rate of the pachyrhizua angulatus tissue culture seedlings cultivated through the method is high, and compared with the situation that seedling raising can be conducted only in February and March in the prior art, by means of the method, seedling raising can be advanced to be conducted from December of previous year, the peak that kudzuvine rhizomes appear on the market in a centralized mode is avoided, the economic benefit is improved, and the time cost is reduced.

Description

technical field [0001] The invention relates to the technical field of plant tissue cultivation of agricultural crops, in particular to a method for cultivating kudzu tissue culture seedlings by using a plant growth lamp. Background technique [0002] Pueraria powder, an alias of Pueraria lobata, also known as dry Pueraria and Gange, is the tuberous root of the perennial vine of the leguminous family Pueraria, because it contains a lot of starch (19-20% in fresh Pueraria), hence the name. Pueraria lobata is a variety with high yield and wide use; while Pueraria lobata is mainly cultivated artificially. Eating kudzu has many benefits to our body. It not only has the functions of promoting yang and relieving muscles, clearing rashes and relieving diarrhea, relieving restlessness and quenching thirst, but also has the effect of clearing away heat and detoxification. At the same time, kudzu has the effect of relieving headaches. Eating kudzu root regularly can also keep us calm...

AI Technical Summary

Problems solved by technology

In view of the low survival rate of kudzu tissue culture seedlings, some people have used fluorescent lamps or fluorescent lamps to supplement light, but the effect is basically invisible.

The growth period of Pueraria pueraria is from October to December. At present, production is limited by the emergence time. Generally, transplanting and planting begin after mid-April, and the harvest will be concentrated in the market in January and February of the second year. Experiments have proved that in In the main production area of ​​kudzu, the climatic conditions in March, April, and May are the period of vigorous vegetative growth of kudzu. Therefore, raising the seedling time to before February can lay a solid foundation for the high yield of kudzu, save time and cost, and get kudzu earlier Pueraria finished products, staggering the peak of the market; however, before February, due to cold weather, low temperature, insufficient light and other reasons, resulting in poor cultivation effect and low quality of pueraria tissue culture seedlings, mainly manifested in the low survival rate of seedlings, surviving seedlings due Affected by factors such as insufficient temperature and effective light intensity, problems such as slender stems, excessive growth, and low transplanting resistance appeared. In production, there was also a method of increasing the temperature in the shed to improve the survival rate of tissue culture seedlings. High, causing a large number of fungal infections in tissue culture seedlings, and it is often difficult to suppress them by spraying carbendazim and other drugs

Directly affect the time and quality of field transplanting, and increase the production cost

[0004] In order to solve the shortcomings in the prior art, the present invention provides a new method for cultivating kudzu tissue culture seedlings, which effectively solves the problem of low survival rate and insufficient effective illuminance of kudzu tissue culture seedlings before February every year in the past. There are problems such as thin stems, excessive growth, and low transplanting resistance.
