Cultivation method for organic greenhouse green vegetables

Abstract

The invention discloses a cultivation method for organic greenhouse green vegetables. The cultivation method comprises the following steps of 1 land selecting and land preparing, 2 greenhouse erecting, 3 seed processing, 4 seeding, 5 humidity managing, 6 seedling thinning, 7 topdressing, 8 temperature controlling and 9 harvesting. When the green vegetables are planted by adopting the method, the pest and disease damage incidence rate is decreased, utilization of chemical pesticides is avoided, and safety and quality of the green vegetables are guaranteed; compared with the prior art, the germination rate is increased by about 5%-8%, germination is advanced, the yield per mu of the green vegetables is increased by about 3%, and the eating mouthfeel is better.

Description

technical field [0001] The invention belongs to the technical field of vegetable greenhouse planting, and in particular relates to a method for cultivating organic green vegetables in a greenhouse. Background technique [0002] Green cabbage, also known as big leaf green and wide bang green cabbage, is a taproot herbaceous plant of the genus Brassica in the family Brassicaceae. It has firm texture, thick leaf stalk, bitter taste, blunt and thick taste, and contains protein, cellulose, iron, selenium and other nutrients, as well as rich vitamin C. In addition, green vegetables have the functions of promoting blood circulation, removing blood stasis, dissipating blood and reducing swelling, and can be used for postpartum congestion and abdominal pain in pregnant women, as well as treating boils and erysipelas. [0003] With the development of greenhouse planting technology, green vegetables are more and more valued by vegetable farmers due to their advantages of high yield an...

Problems solved by technology

But it has the following defects: 1) the seeds are not treated, the emergence rate depends on soil fertility and seed quality, it is difficult to ensure the stability of the emergence rate; , It is unavoidable to remove the disease during the growth of vegetables, but when the disease occurs, chemical pesticides are usually used for spraying and control; 3) The planting time of this method is too early, and according to common sense in the field, planting too early will cause bolting and reduce 4) This method does not control light, temperature and humidity, and these factors are extremely important to the growth of green vegetables when planting in greenhouses.

It can be seen from this that although the above-mentioned patent discloses a solution for growing vegetables in greenhouses, the production and quality of vegetables grown in greenhouses cannot be improved due to the fact that the specific planting process uses conventional steps.
