Cultivation method for planting summer cress in vegetable greenhouse

Abstract

The invention relates to a cultivation method for planting summer cress in a vegetable greenhouse. The cultivation method comprises the following steps of: (1) selecting high-temperature-resistant variety; (2) forcing germination of seed stems; (3) covering with a 50-70% sunshade net; (4) plowing and finishing field surface to be flat, smooth, mashed and mature; (5) spreading and arranging the seed stems; (6) covering with rice straw; (7) tapping furrow surface with a square hoe or wood board so that the seed stems and the rice straw are coated by a layer of slurry; (8) scientifically managing and controlling fertilizer and water; (9) spraying gibberellin and additionally fertilizing at roots 4-7 days before harvesting; and (10) picking in proper stage. According to the cultivation method provided by the invention, by covering with the sunshade net, cool microclimate is built; by covering with rice straw and slurry, the survival rate of the seed stems is improved; by supplying enough fertilizer, the vegetative growth of cress is promoted; and by spraying gibberellin, the summer cultivation difficulty of cress is better solved. In addition, by adopting the cultivation method provided by the invention, water and drought crop rotation in the vegetable greenhouse is realized, and a simple and efficient new way is found for preventing and controlling continuous cropping drawback.

Description

technical field [0001] The invention relates to a vegetable cultivation method, in particular to a cultivation method for planting summer cress in a vegetable greenhouse. technical background [0002] As watercress is a cool vegetable crop, it is generally planted in autumn, harvested in the current year or delayed in the early spring of the next year and supplied to the market. reproductive growth stage. In summer, cress is planted in rows under conventional management conditions. Due to the high temperature, the sun exposure will cause the stems to lose water rapidly, dry up and die. If a thin water layer is established, the high temperature exposure will cause the seedlings to be scalded. The establishment of a deep water layer will cause the stems to rot due to air-tight anaerobic. Therefore, the survival rate of the stems during summer cultivation is very low. In addition, in high temperature seasons, cress will quickly bolt and turn to reproductive growth, and the g...

Problems solved by technology

In summer, cress is planted in rows under conventional management conditions. Due to the high temperature, the sun exposure will cause the stems to lose water rapidly, dry up and die. If a thin water layer is established, the high temperature exposure will cause the seedlings to be scalded. Establish a deep water layer, and the seed stems will rot due to air-tight anaerobic

Therefore, the survival rate of the stems during summer cultivation is very low

In addition, in high temperature seasons, cress will quickly bolt and turn to reproductive growth, and the growing cress stalks and petiole tissue fibrosis is obvious, the taste is very bad, and only very short tender stems can be eaten, and they must be torn off by hand epidermis of the stalk

Therefore, it is difficult to carry out summer cultivation of cress in production, which cannot meet the consumption demand of the market
