Water-retention and drought-resistant agent, preparation method thereof and application of water-retention and drought-resistant agent in quinoa planting

Abstract

The invention discloses a water-retention and drought-resistant agent, a preparation method thereof and application of the water-retention and drought-resistant agent in quinoa planting, and relates to the technical field of quinoa planting. The water-retaining and drought-resistant agent is prepared from the following raw materials in percentage by weight: 6-9% of a water-retaining agent, 1-3% of a drought-resistant agent, 0.5-1% of a growth promoting agent, 6-9% of an oxygen producer, 20-30% of a binder and the balance of a filler. The water-retention and drought-resistant agent can effectively slow down surface water loss after being used, can release oxygen for growth of seeds 3 days after sowing, remarkably improves the germination rate and the ground breaking rate of the seeds, and has practical significance for solving the problem of low emergence rate in quinoa production in Shanxi region.

Description

technical field [0001] The invention relates to the technical field of quinoa planting, in particular to a water-retaining and drought-resistant agent, a preparation method thereof and an application in quinoa planting. Background technique [0002] Quinoa is native to the high-altitude area of ​​the Andes in South America. It is rich in protein, vitamins, polyphenols, flavonoids and other substances with health benefits, and unsaturated fatty acids in the fat contained in quinoa account for more than 80%. It has been paid more and more attention by researchers. [0003] Quinoa is a shallow-rooted crop, especially during the sowing process. If the soil is covered deeply, the quinoa seedlings will not easily break through the soil, resulting in a low seed germination rate. Therefore, it is suitable to sow in shallow areas. However, quinoa is introduced to Shanxi and other arid or semi-arid areas. Some practical problems were encountered in the process. For example, the clim...

Problems solved by technology

[0003] Quinoa is a shallow-rooted crop, especially during the sowing process. If the soil is covered deeply, quinoa seedlings will not easily break through the soil, resulting in a low seed germination rate. Therefore, it is suitable to sow in shallow areas. However, quinoa is introduced to Shanxi and other arid or semi-arid areas. Encountered some practical problems in the process

For example, the climate in Shanxi is dry, the average annual precipitation is small, the surface water evaporates greatly, and the humidity is low. After sowing quinoa seeds in shallow areas, due to the dry surface and low water content, quinoa seeds are under drought stress, which greatly affects germination. rate, resulting in reduced crop yields

Because it is particularly important to ensure sufficient water supply or improve its drought resistance during the germination stage of quinoa seeds to increase yield in the later period, and usually there are difficulties in irrigation and untimely water supply in arid or semi-arid areas, so the promotion of planting in quinoa In the process, providing a method to improve the emergence rate of quinoa is a problem that those skilled in the art need to solve urgently
