A kind of regenerative rice regeneration season promoting germination fertilizer and fertilization equipment

Abstract

The invention relates to a kind of fertilization equipment for promoting budding fertilizer in the ratooning rice regeneration season, which comprises an equipment support, and a secondary fertilizer discharge device and a gas distribution device are arranged on the equipment support, and the secondary fertilizer discharge device includes a silo, a fertilizer discharge wheel and a feeding box , the outer periphery of the fertilizer discharge wheel is provided with material distribution grooves, and a fertilizer discharge box is arranged in the lower material box. The secondary fertilizer discharge device also includes a pair of fertilizer discharge transmission shafts. A row of fertilizer gears and a second fertilizer row gear, a discharge gap for storing germination-promoting fertilizers is formed between the cooperating tooth tops and corresponding tooth roots of the first fertilizer row gear and the second fertilizer row gear, and the gas distribution device includes The exhaust fertilization pipe connected with the feed port of the corresponding fertilizer discharge box, and the discharge port of each exhaust fertilization pipe is provided with a fertilizer discharge nozzle with the outlet facing downward. The invention provides a budding-promoting fertilization equipment for ratooning rice regeneration season which has good uniformity of fertilizer discharge and can avoid residual stubble from affecting the fertilization process and the growth of regenerated buds.

Description

technical field [0001] The invention relates to a fertilization device for promoting budding fertilizer in the ratooning rice regeneration season in the technical field of rice fertilization. Background technique [0002] Raising rice means planting rice that is harvested twice in one crop. After the first season of rice is harvested, the rice piles are used to re-emerge seedlings and grow ears, and then harvest for another season. In order to ensure stable and high yield, it is very important to topdress the rice timely to meet the nutrient requirements of the rice after harvesting the first season of rice. The application of germ-promoting fertilizer can provide sufficient nitrogen for the growth of regenerated rice buds, thereby promoting the germination of regenerated buds to form ears. Increase the yield of ratooning rice. [0003] The germination-promoting fertilization period of the ratooning rice in the middle and lower reaches of the Yangtze River in my country is ...

AI Technical Summary

Problems solved by technology

The traditional topdressing of ratooning rice is mainly based on manual fertilization, which takes up a lot of agricultural labor and has low work efficiency. The human body is directly in contact with chemical fertilizers, which will also affect the health of the body.

Artificial fertilization, uneven spreading, excessive use of chemical fertilizers, causing environmental pollution, compacting the soil, and reducing soil quality

In addition, after the first season of ratooning rice is harvested, there will be rice stubble above the stalks of ratooning rice, which will not only affect the smooth fall of the germ-promoting fertilizer on the ground, but also affect the growth of ratooning rice buds. technology, the stubble can only be collected and processed manually, and the whole process is time-consuming and laborious

[0004] The mechanical topdressing in the prior art has the following disadvantages: 1) The operating width of the centrifugal disc fertilizer spreader cannot be precisely controlled, which will cause missed application or reapplication in some areas, thereby affecting the quality of fertilization operations; The toothed general-purpose external groove wheel type fertilizer machine will have problems such as broken strips and large pulsation when the amount of fertilizer discharged is small or the rotation speed of the fertilizer wheel is low; Cause a certain degree of rolling on the field, which has a greater impact on growing crops
