Allium mongolicum regel planting method

Abstract

The invention discloses an allium mongolicum regel planting method and belongs to the field of agricultural planting. The method is characterized in that after the last quire of allium mongolicum regel in a planting season is harvested, the allium mongolicum regel in the field is dug by root, the field is hacked and leveled in the following spring, a drilling method is used, seedlings can emerge in 15 days to 20 days after sowing, stubble and rotten leaves are removed, and allium mongolicum regel plants are immersed through biological agents. The method has the advantages of being environmentally friendly, pollution-free, capable of achieving continuous multi-year organic production of allium mongolicum regel in the same field, free of main pest and disease damages and good in quality of the planted allium mongolicum regel.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and relates to a method for planting shallots. Background technique [0002] Sand onion (A.mongolicum Bgl) is a perennial herb of Liliaceae, with needle-shaped stems and leaves and small white flowers. It is a companion plant of desert meadow plants. So it is called sand onion. Sand onion can be used in various delicacies and has certain medicinal value. Due to the sporadic growth and distribution of sandy onion in the sandy Gobi Gobi, it is extremely difficult to harvest, and limited by its biological characteristics, its output will increase or decrease with the different climates of the year. In years with abundant rainfall, the output can increase significantly. Minqin County, surrounded by the Tengger Desert and the Badain Jaran Desert, is one of the main producing areas of scallions, with an annual output of 500 tons of scallions. [0003] For a long time, the method of planting sand...

Problems solved by technology

[0003] For a long time, the method of planting sand onions has been one-time sowing, and continuous harvesting during the growth period. It is better to keep the interval between two cuts at harvesting for about one month, so as to meet the mutual operation and needs of underground and aboveground nutrients. The multi-year production of sand onion continuously overwinters and reproduces in the soil, and continues to accumulate. The number is increasing, and the losses caused will become more and more serious; therefore, the continuous production of sand onion in a large area for many years now requires chemical control, otherwise there will be no harvest

Especially the larvae of "a variety of mosquitoes and flies and other pests that harm the bulbs and roots of sand onion underground, they live underground, and the types and proportions of major pests vary greatly in different years, different regions, and different seasons. Large, it is very difficult to use drugs to prevent and control. Use low-toxicity and low-residue pesticides with short duration for control. If the pesticides are applied early, the pests will not come out. Illegal use of low-priced, highly toxic or even highly toxic pesticides with a long lasting effect to prevent and control scallion root maggots not only pollutes the soil, but also increases the cost of prevention and control
