Problems solved by technology

[0003] There are some defects in the existing planting methods of asparagus, which lead to thin diameter of asparagus, low yield, and easy occurrence of diseases and insect pests
Asparagus diseases mainly include stem blight, brown spot, sclerotinia, root rot, blight, rust and other diseases caused by fungi; insect pests include grubs, mole crickets, seed flies, needleworms and other underground pests and Spodoptera litura At present, pesticides are mainly used to prevent and control pests and diseases, which can easily lead to pesticide residues on the surface of asparagus tender stems. The surface of asparagus tender stems is scale-like leaves. The pesticides are not easy to wash off, and eating them will affect human health.

Embodiment 1

[0027] (1) Pretreatment: Soak the seeds at 22°C for 2 days before sowing, and change the water every morning and evening; place the soaked seeds at a low temperature of 2°C for 60 days to facilitate the completion of the dormancy period;

[0028] (2) Soil preparation: Evenly bury 1600kg of organic fertilizer and 16kg of nitrogen, phosphorus and potassium compound fertilizer per mu of land, and plow 30-40cm deep in the whole field to mix the soil and fertilizer evenly;

[0029] (3) Dense planting cultivation: Ditching and planting with a row spacing of 0.8-1.0m, a plant spacing of 20-25cm, and 2800-3000 plants per mu;

[0030] (4) Fertilizer and water management: In the first month after planting, topdress 17kg of urea per mu, and then topdress 14kg of nitrogen, phosphorus and potassium compound fertilizer per mu per month; Fertilizer 1600kg, nitrogen, phosphorus and potassium compound fertilizer 15kg, topdressing nitrogen, phosphorus and potassium compound fertilizer 10kg per ...

Abstract

The invention discloses a pest-prevention and disease-resistant planting method for asparagus and relates to the technical field of agriculture. According to the method, modification treatment is conducted on chaff charcoal to make the chaff charcoal have certain antibacterial activity, and at the same time, nutrient components in organic fertilizer are fixed in the chaff charcoal through the interaction force of chemical bonds and physical adsorption, so that loss and waste of the organic fertilizer are avoided; when the organic fertilizer is mixed with soil, the organic fertilizer is released and absorbed by the asparagus, and the content of vitamin C and selenium in the asparagus is increased; a dispersing agent can uniformly disperse the organic fertilizer in the chaff charcoal and keep the stability of components, so that the organic fertilizer has certain antibacterial performance. The method adopts the chaff charcoal and feces of livestock and poultry as raw materials, the costis low, and benefits are high; moreover, extracts of traditional Chinese medicine are added, and strong resistance to pests and diseases is achieved.

Description

Technical field: [0001] The invention relates to the technical field of agriculture, in particular to an insect-proof and disease-resistant asparagus planting method. Background technique: [0002] Asparagus, also known as asparagus, is a high-end nutritious and healthy vegetable loved by consumers. It is tender and delicious, rich in nutrition, and unique in flavor. It is known as the "king of vegetables". It is native to the temperate zone. Dormant, in spring, the tender stems are drawn from the underground scale bud plate to form the yield. After harvesting for a period of time, let them grow, and harvest the tender stems again in the spring of the next year. Asparagus is a perennial plant, planted in one year, and can be harvested continuously for 8-10 years. [0003] There are some defects in the existing planting method of asparagus, which leads to thin diameter of asparagus, low yield, and easy occurrence of diseases and insect pests. Asparagus diseases mainly inclu...
