Embodiment Construction

[0012] Such as figure 1 The shown seedling tray for orderly throwing and planting of rice is composed of 145 seedling holes 1 which are rotated 180° in sequence, and each seedling hole 1 is composed of three seedling pits 2 arranged in an equilateral triangle. Three seedling-raising pits in each seedling-raising hole 1 are recessed 1 / 3 to 1 / 2 of the depth of the hole wall downwards in two adjacent places, so that these three seedling-raising pits form partially connected triple holes, so that the The root system of the three pits colludes to form a whole, which is beneficial for throwing or placing. The center of three consecutive holes does not have concave, therefore constitutes a convex point or bump 4, and the height of the convex point is lower than the depth of the pit, which can ensure that the seeds are evenly distributed in 3 seedling pits during sowing. The bottom of each breeding pit 1 is provided with a small hole 3 for regulating moisture. The pit is 1.6 cm dee...

Abstract

The invention belongs to the field of rice cultivation, and relates to an accurate triple-hole rice seedling cultivation technology. The accurate triple-hole rice seedling cultivation method comprises the following steps of: raising triple-hole group rice seedlings, and performing point slinging or swing planting. Triple-hole plastic plate dry raising control is adopted for cultivating strong seedlings, so that one third to two thirds of slinging planting holes are reduced, the seedling slinging or swing planting speed is improved, the labor force is remarkably saved, the labor cost is reduced, the rice seedlings are distributed uniformly, holes in a field are reduced, the holes have good ventilation and light transmission, the individual seedlings are robust, the group structure is optimized, high yield or ultrahigh yield of rice can be stably realized, the yield is increased by over 10 percent, and the effect is increased by over 15 percent.

Description

technical field [0001] The invention belongs to the field of rice cultivation, and relates to a precision cultivation technique for rice seedlings with three consecutive holes, which can reduce the number of planting holes per mu, reduce labor intensity and shorten working time, and is beneficial to increase, high and super-high yield of rice. Background technique [0002] Present paddy seedling throwing mainly adopts single-hole plastic tray seedling raising, with 3-5 seedlings in every hole. There are 18,000 to 25,000 holes per mu, and the number of holes is too many, which wastes labor, and the seedlings are not evenly distributed, the gaps between the holes are small, the ventilation and light transmission are poor, the pests are heavy, and they are easy to lodging, which affects the high yield and quality of throwing rice. Stable production. Contents of the invention [0003] In order to solve the problems of the existing rice seedling throwing holes (clusters, the s...
