Seed treatment method for alleviating continuous cropping obstacle of quinoa

Abstract

The invention belongs to the technical field of crop planting, and provides a seed treatment method for alleviating a continuous cropping obstacle of quinoa in order to solve the problems that a yieldis reduced and serious continuous cropping obstacles exist in current continuous cropping planting of the quinoa. The method comprises the following steps: screening seeds and performing disinfection, wrapping the disinfected seeds with microbial spore powder, wrapping the microbial spore powder with a swelling layer, wrapping the swelling layer with a water-absorbing layer, and performing forming to complete the steps. According to the method provided by the invention, the microbial spore powder for alleviating continuous cropping planting of the quinoa is added, breeding is performed undersuitable environmental conditions, the soil microenvironment is improved, the microenvironment suitable for growth of the quinoa is reconstructed, so that the problem of continuous cropping planting of the quinoa can be effectively solved, and the current situation of land resource shortage can be alleviated; the method has low costs, saves labor force, does not relate to pesticides and fertilizers, has no pollution to the environment, and guarantees green pollution-free cultivation of the quinoa; the method can effectively alleviate the problem of the continuous cropping obstacle of the quinoa, the sowing depth of continuous cropping planting is 3-4cm, the depth of a root system reaches 25cm when the quinoa is mature, the plant uniformity is better, and the yield is restored to 95-97% ofthat of planting in a first year; and the method is also applied to first-year planting and multi-year planting.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a seed treatment method for alleviating the obstacle of continuous cropping of quinoa, which overcomes the obstacle of continuous cropping of quinoa. Background technique [0002] Quinoa is a traditional crop in South America, with strong resistance to stress. Because of its comprehensive and balanced nutrition, especially rich in protein, vitamins, mineral elements, etc., it has been called the "mother of food" and "nutrition gold". Since 2010, quinoa Since it was introduced to China in 2016, it has developed rapidly and brought great economic benefits to local farmers. By the end of 2016, Shanxi, Inner Mongolia, Gansu, Qinghai, Ningxia, Yunnan, Hebei and other provinces have planted large areas, but due to Driven by economic interests, farmers continue to plant in the same plot year after year. Although the yield has dropped sharply, they continue to plant, wh...

[0002] Quinoa is a traditional crop in South America, with strong resistance to stress. Because of its comprehensive and balanced nutrition, especially rich in protein, vitamins, mineral elements, etc., it has been called the "mother of food" and "nutrition gold". Since 2010, quinoa Since it was introduced to China in 2016, it has developed rapidly and brought great economic benefits to local farmers. By the end of 2016, Shanxi, Inner Mongolia, Gansu, Qinghai, Ningxia, Yunnan, Hebei and other provinces have planted large areas, but due to Driven by economic interests, farmers continue to plant in the same plot year after year. Although the yield has dropped sharply, they continue to plant, which eventually leads to serious consequences such as extinction, and also causes aggravation of diseases and insect pests. Studies have shown that root maggots in plots that have been planted for more than two years , Leaf fly, beet tube beak weevil and other diseases and insect pests have aggravated sharply, basically leading to extinction

[0003] To this end, a large number of scientific researchers have carried out related research, and the effect of taking measures such as soil disinfection and increasing base fertilizer is not obvious. Because crop continuous cropping obstacles are problems in the world, the reasons are affected by various factors (root system exudates, allelopathic effects, changes in soil micro-ecological environment, soil-borne diseases), and quinoa is an introduced crop, and there are few related studies on it, especially root exudates and changes in soil micro-ecological environment, there is currently no data for reference , and due to the uncertainty of the field environment, the beneficial microorganisms contained in some microbial fertilizers may play a significant role in the laboratory environment, but it is difficult to survive in the field environment

[0004] Therefore, there are no reports about solving or alleviating the continuous cropping obstacles of quinoa. There are some reports about the treatment technology to promote the germination rate of quinoa, but it only involves water absorption to increase the germination rate of quinoa, and there is still some pollution to the environment.
