Yield-increasing cultivation method for asparagus

Abstract

The invention discloses a yield-increasing cultivation method for asparagus. The method comprises the following steps: A, breeding seedlings: sowing the seedlings in a flowerpot matrix in a greenhouse for breeding the seedlings at the normal temperature in the middle ten days of April in the middle and lower reaches of Yangtze river; B, greenhouse treatment before transplanting: ditching a parcel of a rice field in the greenhouse, applying an organic fertilizer and a compound fertilizer into a ditch and covering the ditch with soil after fertilizer application; C, plant transplantation: during transplanting, covering the ground by a black mulch and carrying out trickle irrigation; and D, carrying out field management: wiping out parts of plants growing over the ground, carrying out conventional disinfection, and applying the fertilizer; further increasing an arched shed on crops in the greenhouse; and E, carrying out harvesting. By adopting the method, conventional marketing time is staggered. According to the cultivation method which firstly breeds seedlings and then transplants the seedlings, the cultivation method is scientific and reasonable and the temperature is reasonably controlled. On the one hand, the method is adaptive to the growth condition of asparagus, so that the output and quality of asparagus are improved; on the other hand, plant diseases and insect pests are effectively reduced, the input cost is lowered, the yield is improved by 30-50% compared to that of a conventional method, and the economical benefit is improved as the asparagus is harvested 2-3 months in advance.

Description

technical field [0001] The invention relates to a method for cultivating asparagus, in particular to a method for cultivating asparagus to increase production, and belongs to the technical field of agricultural planting. Background technique [0002] Asparagus is one of the top ten famous dishes in the world. Asparagus is rich in various amino acids, proteins and vitamins, and its content is higher than that of ordinary fruits and vegetables, especially asparagine and trace elements such as selenium, molybdenum, chromium and manganese in asparagus. , has the effect of regulating the body's metabolism and improving the body's immunity. It has a strong inhibitory effect and pharmacological effect in the prevention and treatment of hypertension, heart disease, leukemia, blood cancer, edema, cystitis, etc.; therefore, asparagus is very popular. People's love and welcome. Traditionally, the middle and lower reaches of the Yangtze River generally adopt open-air cultivation and ext...

[0002] Asparagus is one of the top ten famous dishes in the world. Asparagus is rich in various amino acids, proteins and vitamins, and its content is higher than that of ordinary fruits and vegetables, especially asparagine and trace elements such as selenium, molybdenum, chromium and manganese in asparagus. , has the effect of regulating the body's metabolism and improving the body's immunity. It has a strong inhibitory effect and pharmacological effect in the prevention and treatment of hypertension, heart disease, leukemia, blood cancer, edema, cystitis, etc.; therefore, asparagus is very popular. People's love and welcome. Traditionally, the middle and lower reaches of the Yangtze River generally adopt open-air cultivation and extensive management, which on the one hand leads to low yields of asparagus and delays in market time. On the other hand, pests and diseases occur frequently, and pesticides have to be used to eliminate diseases. , not only wasted energy, but also increased input costs, and more importantly, reduced the quality of asparagus
