Embodiment Construction

[0012] like figure 1 , a kind of seedling-raising dish that is used for the orderly throwing of rice seedlings shown in 2 and is made up of orderly arrangement of seedling holes, and each seedling hole 1 is formed by the arrangement of two seedling pits 2, and each seedling hole Two seedling-raising pits 2 in 1 are adjacent to 1 / 2 of the depth of the pit wall downward depression, so that these two seedling-raising pits form a partially connected Erlian hole, so that the seedlings bred in this way, the roots of the two pits are connected to form a whole, such as image 3 , which is good for throwing or placing plants. The bottom of each seedling raising hole 2 is provided with aperture 3, is used for regulating moisture. The pit is 1.6 cm deep.

[0013] Use two-hole seedling trays to cultivate strong seedlings of the right age, strictly control chemical control and implement drought management, and the seedling age is 25-30 days, with an average of ≥0.5 tillers per seedling...

Abstract

The invention belongs to the field of rice cultivation, relates to an orderly accurate cultivation method of two-connected-hole rice seedlings. The method has the advantages of reducing the number of throwing and bow raising holes per mu, lowering labor intensity, shortening operation time, performing throwing and bowl raising conveniently and orderly, being favorable for yield increase, high yield and super high yield of rice. According to the method, two-connected-hole clustered rice seedlings are cultivated firstly, then point throwing or bowl raising is carried out; the roots of two-connected-hole rice seedlings are integrated into a whole, and therefore the throwing and bow raising speed can be increased, the working time is saved, the cost is reduced, the number of holes in paddy field is small, the rice seedlings are distributed orderly to achieve good ventilation and light transmission effects, which is beneficial to the high yield and super high yield of rice.

Description

technical field [0001] The invention belongs to the field of rice cultivation, and relates to a precise cultivation technology for rice seedlings with two continuous holes, which can reduce the number of throwing and planting holes per mu, reduce labor intensity and shorten working time, and is beneficial to increase, high and super high yield of rice. technical background [0002] Present paddy seedling throwing mainly adopts single-hole plastic tray seedling raising, with 3-5 strains of seedlings in every hole. There are 18,000 to 25,000 holes per mu, and too many holes are wasting labor, and the seedlings in the field are unevenly distributed, the gaps between the holes are small, and the light transmission and ventilation are poor, which affects the high and stable yield of throwing rice. Contents of the invention [0003] In order to solve the problems of the existing rice seedling throwing holes (clusters, the same below) as many, large labor costs, uneven distributi...
