Embodiment 1

[0042] A method for cultivating Sagittarius sagittarius in early spring in a greenhouse covered with ridges and covered with black film, comprising the following steps:

[0043] (1) Seedling management

[0044] The water bed of the seedling bed is injected with a water depth of 24-26cm one week before the seedling;

[0045] Take sturdy, pest-free, 195-205 terminal buds / kg, break off from the corm, place them in a double-film water bed for seedling cultivation, keep the shed airtight during the seedling raising period, to increase the water temperature in the shed;

[0046] (2) Soil preparation and fertilization

[0047] Plowing and freezing felling before winter, and 45 tons / ha of decomposed pig manure or cow manure, 45% (N:P:K=15:15:15) ternary compound fertilizer 300 kg / ha as base fertilizer 15 days before transplanting , shallow rotary rake flat rake fine, rake depth 8 ~ 10cm;

[0048] (3) Field modeling

[0049] After soil preparation and fertilization, ridges: ridge h...

Abstract

The invention discloses a greenhouse early spring arrowhead ridging and black film covering cultivation method. The greenhouse early spring arrowhead ridging and black film covering cultivation method comprises the following steps that (1), soil preparation and fertilization are carried out; (2), field modeling and ridging are carried out, specifically, the ridging height ranges from 10 cm to 12 cm, the ridging width ranges from 60 cm to 65 cm, the furrow width ranges from 25 cm to 30 cm, and the furrow depth ranges from 10 cm to 15 cm; (3), furrow irrigation is carried out, and water is irrigated along the furrows until the water just submerges the ridge surfaces; (4), black film covering and drip irrigation are applied, all ridge surfaces are covered with the black film, and drip irrigation water belts are laid between planting rows under the film; and (5), field planting is carried out. According to the greenhouse early spring arrowhead ridging and black film covering cultivation method, water and labor are saved, continuous cropping obstacles are relieved, diseases are greatly reduced, and the yield and quality are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of agricultural production, and relates to a method for cultivating Sagittarius early spring in greenhouses. Background technique [0002] Serious obstacles to continuous cropping of protected vegetables after years of planting, the most effective and fast way to alleviate it is through water (humid) dry rotation. Sagittarius, as a high-yield and high-efficiency aquatic vegetable crop, is an important option for the high-efficiency rotation mode of facility vegetables. The traditional cultivation of Sagittarius is flood irrigation in summer and autumn in the open field. Generally, it is planted in April, harvested in November, and a market gap is formed in June; in terms of management, it is required to maintain a shallow water layer of 5-7 cm in the field during the entire growth period of Sagittarius. In the hot season, the field water level needs to be deepened to 8-10 cm. Traditional sagittarius cultiv...
