Description

Efficient one-hand holding type agricultural seeder

Technical Field

The invention relates to the technical field of agriculture, in particular to an efficient single-hand holding type agricultural seeder.

Background

According to the crop species, variety characteristics, planting system, cultivation mode and requirements for environmental conditions, the proper sowing time, sowing quantity and sowing method are selected, and seeds are sowed into soil layers with certain depth manually or by machines. Whether sowing is proper or not directly influences the growth and the yield of crops.

Timely sowing is an important measure for ensuring that crops obtain favorable climatic conditions, full and strong seedlings, normal growth of plants and timely maturity in each growth period from seed germination, seedling emergence to maturity. The sowing optimum period of different crops is mainly determined by variety characteristics, temperature, moisture, cultivation system, soil texture and topography. The weight of seeds sown per unit area of land is in kilograms per hectare. The suitable seeding rate is the premise of reasonable close planting. Generally, the method is calculated according to indexes such as density (number of plants) per hectare, thousand seed weight, germination rate, field emergence rate and the like. The sowing depth is related to the germination of seeds, the quality of the emergence of seedlings and the growth of seedlings. The proper depth should be determined according to the crop, soil and climate conditions. The sowing mode is determined according to the crop species, the growth characteristics, the cultivation system, the planting density, the sowing machine and other factors. Generally, the method is divided into broadcast sowing, drill sowing and dibbling.

To individual user, traditional seeding mode is mainly with broadcasting a seed to pre-buried hole with one hand, though need not just can accomplish the task with the help of mechanical equipment, has nevertheless led to holistic seeding efficiency greatly reduced, and it is very time-consuming and energy-consuming to waste time, and the seeding equipment who uses on the market is too complicated again, and the structure is complicated must lead to the price high, can not ensure moreover that the seed can deviate from one grain, carries inconveniently, influences the rate of utilization.

There is therefore a need to provide an efficient single-handed holding agricultural planter that addresses the above problems.
