Embodiment Construction

[0026] 1. Variety selection

[0027] The varieties suitable for planting in our province include Dajihuang, Daguqing, Jianye, Siyong, Dajiqing and so on.

[0028] 2. Cultivation season

[0029] Greenhouse cultivation can basically produce and supply year-round. In order to obtain higher economic benefits, it should be sown in October-December and listed from December to March of the next year.

[0030] 3. Soil preparation and fertilization

[0031] Water spinach grows fast, has strong branching ability, and needs more fertilizer and water. It is advisable to apply enough base fertilizer when planting. Generally, 1500-2000 kg of decomposed organic fertilizer and 100 kg of plant ash are applied per mu. 130-150 cm furrow.

[0032] 4. Seed soaking and germination

[0033] The seed coat of water spinach seeds is thick and hard. If they are sown directly, they will germinate slowly due to low temperature. If they encounter long-term low temperature and rainy weather, they will c...

Abstract

Provided is a winter greenhouse water convolvulus cultivation technology, characterized by comprising the following steps: selecting varieties, selecting a cultivation season, preparing land and applying fertilizer, soaking seeds and forcing buds, sowing, managing a greenhouse, and harvesting. The technology solves a problem that a conventional water convolvulus cultivation mode is low in yield, and the winter greenhouse water convolvulus cultivation technology is realized.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a technology for cultivating water spinach in winter greenhouses. Background technique [0002] Water spinach likes high temperature and humidity, has strong heat resistance, and is not resistant to frost. When it encounters frost, the stems and leaves will die. The optimum temperature for growth is 25-30°C, and the growth stagnates below 10°C. Therefore, plastic greenhouses should be used for off-season cultivation in winter. At present, my country's water spinach cultivation mainly adopts traditional plastic film mulching and open-field cultivation. The disadvantages are: concentrated market of water spinach, resulting in price squeeze competition, short market supply period, and the traditional cultivation mode has low yield and poor income. Contents of the invention [0003] In order to solve the problem of low yield in the traditional water spinach cultivation mode, the i...
