Problems solved by technology

However, the existing machine-transplanting technology cannot realize that the number of seedlings per cluster is basically the same
In addition, hybrid rice seeds are expensive, and the seedling rate of hybrid rice machine-transplanted seeds is low, resulting in higher seed costs

Embodiment 1

[0023] The single-cropping rice and continuous-cropping late rice quantitative seeder transplanting experiments were carried out on Yongyou 1540. The planned yield target is 600-700kg, the size of machine-planted planting is 30×18, and the seedling age is 20d. According to the yield target, the average number of machine-planted seedlings per clump is 2 seedlings. The seedlings are designed for 34 times.

[0024] 1) Calculation of live tree rate of machine-transplanted seedlings

[0025] According to the accumulation of data in the continuous cropping late rice season, when the seedling age of continuous cropping late rice was calculated for 20 days, the rate of machine-planted 14 and 16 live seedlings per clump was 97.9% and 96.3%, respectively.

[0026] 2) Calculation of utilization rate of machine-planted seedlings

[0027] According to the accumulation of data in the continuous cropping late rice season, when the seedling age of continuous cropping late rice was calculate...

Abstract

The invention belongs to the technical field of rice machine-planting and planting, and discloses a quantitative machine-planting method for rice. According to the basic number of machine-planted seedlings per hole (cluster) under a specific yield target, according to the sowing method, the survival rate of machine-planted seedlings is calculated and the machine-planted seedlings are The utilization rate and the seedling rate of the seedlings in the seedling trays are used to determine the number of seeds sown in the trays. Positioning, quantitative and uniform sowing are carried out by means of hole seeding and drill seeding, and the machine-planting method of corresponding horizontal seedling times is matched. Realize the accurate digitization of seeding rate and improve the uniformity of the distribution of machine-planted seedlings.

Description

technical field [0001] The invention belongs to the technical field of rice machine transplanting and planting, and in particular relates to a rice quantitative machine transplanting method. Background technique [0002] With social and economic development, the transfer of rural labor and the increase in cost, rice planting has developed from manual rice transplanting to mechanized rice transplanting. The conventional rice machine transplanting technology adopts the seedling tray raising and the blanket seedling machine planting. The seed sowing of the rice machine transplanting tray has the defect of uneven seed distribution. In some areas, there are many seedlings, and the unit area is very dense. In some areas, there are few seedlings and few seedlings. At the same time, there is the problem of inconsistency in the growth size and height of the seedlings in the seedling tray. Due to the inconsistent size of the seedlings and the large difference in the number of seedli...
