Method for rapid water spinach propagation in matrix under greenhouse seedbed in winter

Abstract

The invention discloses a method for rapid water spinach propagation in a matrix under a greenhouse seedbed in winter. The method comprises the following steps that 1, water spinach culture bed is manufactured, including greenhouse disinfection, matrix processing and preparation and culture bed manufacturing; 2, cutting shoot preparation and cutting are performed, wherein older cutting shoots at lower portions are selected in the first and middle ten-day of October, one section is sheared off every 3 joints, the length of the joint at the basic portion is controlled to 0.5-1 cm, and cuttage is performed on the culture bed after treatment with a rooting agent and a bactericide; 3, management is performed after cuttage, including moisture management, nutrition management, temperature management, light adjustment and diseases and pest prevention and control; 4, harvesting is performed, wherein tender shoots are picked when the water spinaches grow to 20-30 cm. By the adoption of the method, the stereoscopic space of a greenhouse, greenhouse energy sources and abandoned matrixes can be reasonably utilized to the most degree, the income of the green house per unit area can be increased, and safe and green water spinach supply in winter is achieved.

Description

technical field [0001] The invention relates to the field of agricultural cultivation, in particular to a method for rapidly propagating water spinach with a substrate under a greenhouse seedbed frame in winter. Background technique [0002] Water spinach is rich in potassium, calcium, chlorine, niacin, vitamin C, etc. It has the functions of clearing away heat and detoxification, diuresis and dehumidification, reducing fat and preventing cancer. Water spinach likes high temperature and humid environment. The suitable temperature for the growth of vine leaves is 25℃~30℃, and it can tolerate high temperature of 35~40℃. The vine leaves grow slowly below 15℃, and the vine leaves stop growing below 10℃. The stems and leaves are dead. Due to its growth characteristics, it is suitable for cultivation in summer and autumn, and there are no facilities that cannot meet the conditions for its growth in winter. In winter, the use of greenhouses for off-season soilless cultivation of ...

AI Technical Summary

Problems solved by technology

This technology aims at problems such as the shortage of water spinach in winter, the three-dimensional space of winter greenhouse seedling cultivation and low energy utilization rate, and the long-season cultivation waste substrate of melons, fruits and vegetables is directly returned to the field to pollute the soil, etc., and provides a method for rapid propagation of water spinach on the substrate under the greenhouse seedbed in winter. Maximize the rational use of the three-dimensional space of the greenhouse, greenhouse energy and waste substrates, increase the income per unit area of ​​the greenhouse, and realize the winter supply and safe green of water spinach
