Embodiment Construction

[0026] In the northern region, taking Beijing as an example, starting from late August, when the average daily atmospheric temperature is below 25°C, the cress seed stems are harvested; the cress seed stems are placed in a shading and moisturizing environment for germination; Apply basal fertilizer to the soil in the greenhouse and plow it to make a flat border, and apply organic fertilizer at an amount of 3000-5000 kg per mu; grow into 20-30cm long, and spread it to the planting furrow in the solar greenhouse according to the amount of 300-400kg per mu; then water it to keep the water holding rate of the plow layer soil above 90%, and the higher water will promote the growth of seedlings. Take root and take root; 10-15 days or after the germinated cress shoots take root in the soil, reduce watering appropriately to keep the soil water holding rate of the soil plow layer at 80-90%; when the seedlings grow to 10cm high, carry out uniform seedling Make up the gap and keep the di...

Abstract

The present invention relates to a water-saving cultivation method of multicrop water dropwort. Said method includes the following steps: making the water dropwort seedstem be budded, applying organic fertilizer in greenhouse, after the seedling is rooted, covering with plastic film, heat-insulating, when the water dropwort is grown to 20-50 cm, harvesting and remaining 1 cm stub, the applying quickly-acting fertilizer to make plant short stem sprout and form new seedling, promoting growth of new seedling and making secondary harvest.

Description

technical field [0001] The invention relates to a vegetable cultivation method, in particular to a water-saving cultivation method of multi-crop cress. Background technique [0002] Vegetable cress is a characteristic aquatic vegetable in China. Generally, it must be grown in paddy fields with a certain water level. It is planted in autumn and harvested for the market in the same year. It can also be delayed in the early spring of the next year. Cress is mainly planted in the Yangtze River Basin and the south of China, where temperature, sunlight and water resources are relatively abundant. Jiangsu, Zhejiang, Anhui, Jiangxi, Hunan and other provinces have relatively large planting areas. Its planting areas are all in the water network area south of the Huaihe River Basin. Due to relatively poor water resources and too cold winters in the north of the Huaihe River Basin, cress is difficult to survive the winter and cannot be planted. [0003] Before the present invention, cr...
