Rice seed soaking agent and application thereof

Abstract

The invention belongs to the technical field of agriculture, and relates to a rice seed soaking agent and application thereof, particularly a seed soaking agent capable promoting rice seeds to quickly rooting and germination after straws directly return to the field, and application thereof. Every 1L of solvent contains the following solute components: 100-150mg of gibberellin, 25-50mg of indoleacetic acid, 0.1-0.5mg of abscisic acid, 500-1000mg of ammonium bicarbonate and 100-500mg of zinc sulfate. The rice seed soaking agent regulates the physiologic and biochemical functions of the rice seeds by the chemical control technique against the direct sowing planting mode of rice, promotes the rice seeds to quickly rooting and germination after the straws directly return to the fertilized filed, can promote growth development of the rice and improve the quality of the rice due to the components in the seed soaking agent, and has obvious yield increase effect; and the yield increase rate of the rice is up to higher than 10%.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a rice seed soaking agent and an application thereof, in particular to a seed soaking agent for promoting rapid rooting and germination of rice seeds after straw is directly returned to the field and an application thereof. Background technique [0002] Straw returning to the field, as a measure to improve soil fertility and increase production that is generally valued in the world today, is a method of applying straw (wheat straw, corn straw, rice straw, etc.) method. The process of agricultural production is a process of energy conversion. During the growth process, crops consume energy continuously, and also need to continuously replenish energy, and constantly adjust the content of water, fertilizer, air and heat in the soil. The straw contains a large amount of fresh organic materials. After being returned to the farmland, after a period of decomposition, it can be conver...

AI Technical Summary

Problems solved by technology

[0013] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a rice seed soaking agent, which can regulate the physiological and biochemical functions of the seeds through chemical control technology, and promote the rapid rooting and germination of rice seeds, and is used to solve the problem of direct return of straw to the field in the prior art. Afterwards, the soil carbon-nitrogen ratio increases, microorganisms and rice seedlings compete for nitrogen together, and the nitrogen supply capacity of rice seeds is insufficient for germination; at the same time, the soil is too loose, with many large pores, and the seeds cannot be in close contact with the soil, which affects germination and growth, and the roots are not firm. Problems with yellow seedlings, dead seedlings, and yield reduction
