Integrated equipment for aeration, seed soaking and germination accelerating of rice in cold region

Abstract

The invention provides integrated equipment for aeration, seed soaking and germination accelerating of rice in a cold region, and relates to the technical field of agricultural machinery. The equipment is composed of a seed soaking water tank, a temperature control part and an oxygen supply part, wherein the seed soaking water tank is connected with pipelines of the temperature control part and oxygen supply part, a heating water pump of the temperature control part is connected with a pipeline of a hot water tank, the inner portion of the heating water tank is provided with an electric heating rod, an input end of the heating water pump is a water inlet end of the temperature control part, and an output end of the heating water tank is a water outlet end of the temperature control part; an output end of an air compressor of the oxygen supply part is connected with a pipeline of an input end of a gas tank, an aeration pipe is placed in the seed soaking water tank, and an output end ofthe gas tank is connected with the a pipeline of the aeration pipe. The integrated equipment has the following advantages that 1, seed soaking and germination accelerating are integrally completed, sothat the cumbersome process of separately performing seed soaking and germination accelerating is eliminated, and the agricultural time is saved; 2, the seed germination rate is high, the bud lengthis neat, and a good condition is created for bud and seed sowing; 3, water for seed soaking is saved, wherein compared with a traditional method, water change during seed soaking is not needed, so that the water for seed soaking is greatly saved.

Description

Technical field: [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to an integrated equipment for increasing oxygen, soaking seeds and accelerating germination of rice in cold regions. Background technique: [0002] Heilongjiang Province is located in a high-latitude area, and the rice growth period is short. Soaking seeds and raising seedlings in an artificial environment is the main means to prolong the rice growth period. Seedling quality is an important guarantee for rice production to achieve high yield. When the water content is lower than 14%, the rice seeds are in a physiological dormancy state. Seed soaking to accelerate germination is to provide suitable environmental conditions for the germination of rice seeds, so that the seeds can obtain the water required for germination and remove germination inhibitors. Seed soaking is an artificial measure to break seed dormancy and promote its germination. At pres...

AI Technical Summary

Problems solved by technology

The seed soaking and accelerating germination device has played a certain effect on improving the quality of bud seeds, but the control of oxygen in the seed soaking process is still limited to "adjusting the air with water". Due to the number of water changes and the oxygenation efficiency of the natural flow of water, the oxygen supply effect on rice seeds is limited.

In addition, the problem of uneven temperature field distribution in the seed box has not been effectively improved

Rice seeds are soaked in seed boxes with low oxygen content and uneven temperature, but there are still problems of low germination rate and uneven germination

After the soaking of this method is completed, high temperature germination is required, and there are many processes.
