Problems solved by technology

But there are obvious defects: one is that the cracking speed and compressive strength of the pelletized coating are not well unified, showing a phenomenon of growing and falling; Seed germination needs enough water to soak the pellets outside the seeds before they can touch the seeds inside, thus causing a time difference for seeds to germinate; the pellets outside the seeds melt and cause the solute concentration around the seeds to be too high and inhibit the pellets. The third is that under the condition of generally moist or relatively dry soil, the emergence period of conventional coated pellets is generally 1 to 4 days later than that of the control

Abstract

A drought-resistant coating agent for rape seeds is prepared from water preserving agent, talc powder, white clay, insecticide, bactericide, KH2PO4, peat and root growing powder through sequential and proportional mixing, pulverizing, and stirring. Its advantages are high cracking speed and compression strength, and high effect to resist drought, disease and pests and make seedlings strong.

Description

technical field [0001] The invention belongs to the field of agricultural rape varieties and cultivation, in particular to a pelletized drought-resistant seed coating agent for rape seeds and a preparation process thereof. Background technique [0002] Drought-resistant and water-retaining agent is a new type of functional polymer water-absorbing material, which can absorb and retain water hundreds or even thousands of times its own weight. Peat itself also has strong water absorption and water retention properties, and is rich in nutrients and plant growth hormones . Applying drought-resistant water-retaining agent and peat to seed coating agent is mainly to solve the drought problem encountered by seeds during germination and emergence. Pelletized coating is a newly developed seed pelletized product in the world. It has the functions of improving seed sowing quality, saving seeds, preventing seedling pests and diseases, and enhancing stress resistance and drought resistan...
