Problems solved by technology

[0004] The purpose of the present invention is to provide a method for machine-transplanted rice seedling raising in dry land, which solves the problems of high cost and large investment in raising seedlings in seedling trays. The interface is coiled to prevent the roots of the seedlings from penetrating into the deep soil, and solve the problems of traditional discless seedlings that are difficult to take seedlings and easy to damage the roots.

Embodiment 1

[0021] A method for raising seedlings without discs in dry land by machine-transplanting rice, comprising the steps of:

[0022] (1) seedling field preparation: select the dry land with fertile soil, convenient irrigation and drainage, and easy management as the seedling field, open the compartment at a width of 1.0m, and compact the bottom surface of the compartment to form the bottom of the bed. After the surface is compacted, the width of the car surface is 90cm, and the soil at the bottom of the car surface forms a dense layer with a thickness of 4cm, so that water and air can pass through freely, and a gutter with a depth of 10cm and a width of 15cm is set between adjacent two compartments;

[0023] (2) Rice seed preparation: the seeds are sun-dried, selected, soaked in medicinal solution, cleaned and accelerated germination, so that the germination rate of the seeds exceeds 90%;

[0024] (3) Preparation before sowing: first use 0.5cm thick PVC partitions to divide the co...

Embodiment 2

[0029] A method for raising seedlings without discs in dry land by machine-transplanting rice, comprising the steps of:

[0030] (1) Seedling field preparation: select the dry land with fertile soil, convenient irrigation and drainage, and easy management as the seedling field, open the compartment at a width of 1.1 m, and compact the bottom surface of the compartment to form the bottom of the bed. The soil with a width of 10 cm around the compartment surface is not compacted. After the surface is compacted, the width is 90cm, and the soil at the bottom of the compartment surface forms a dense layer with a thickness of 5cm, so that water and air can pass through freely, and a gutter with a depth of 13cm and a width of 17cm is set between adjacent compartments;

[0031] (2) Rice seed preparation: the seeds are sun-dried, selected, soaked in medicinal solution, cleaned and accelerated germination, so that the germination rate of the seeds reaches 95%;

[0032] (3) Preparation be...

Embodiment 3

[0037] (1) Seedling field preparation: select the dry land with fertile soil, convenient irrigation and drainage, and easy management as the seedling field, open the compartment at a width of 1.2m, and compact the bottom surface of the compartment to form the bottom of the bed. After the surface is compacted, the width is 100cm, and the soil at the bottom of the compartment surface forms a dense layer with a thickness of 5cm, so that water and air can pass through freely, and a trench with a depth of 15cm and a width of 20cm is set between adjacent compartments;

[0038] (2) Rice seed preparation: the seeds are sun-dried, selected, soaked in medicinal solution, cleaned and accelerated germination, so that the germination rate of the seeds reaches 93%;

[0039] (3) Preparation before sowing: first use a PVC board with a thickness of 0.5cm to divide the car surface into a seedbed with a width of 28cm, then evenly spread a substrate or nutrient soil with a thickness of 4cm on the ...

Abstract

The present invention relates to the technical field of rice planting, in particular to a method for raising seedlings without discs in dry land by machine-transplanting rice, comprising (1) seedling field preparation; (2) rice seed preparation; (3) preparation before sowing; (4) sowing; 5) Seedling field management and (6) transplanting step of seedling lifter; in the present invention, because the bottom of the seedbed bed is compacted to form a dense layer, seedlings are raised above the dense layer to prevent the roots of the seedlings from growing into the dense layer. Existence, the seedling root system grows in the part above the dense layer, it is very easy to take seedlings, which can effectively avoid the problem of damage to the seedling root system; in addition, it has no effect on the growth of the seedlings, and the nutrients, air and water required by the seedlings can circulate freely; In the invention, when seedlings are raised in the seedbed, the partitions are used to separate them, which is convenient for picking seedlings and machine transplanting in the later stage.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for raising seedlings without disks by machine-transplanting dry land. Background technique [0002] With the transfer of rural labor force, artificial rice seedling planting can no longer meet the requirements of my country's social and economic development. The traditional rice farming technology based on hand-transplanted rice seedlings has low production efficiency, low labor productivity, and high labor intensity, which restricts the development of rice production. In production, there is an urgent need for labor-saving, labor-saving, high-yield, and efficient modern rice production technology with mechanized operations as the core, especially the machine-transplanted rice technology. In recent years, with the support of policies, my country's rice machine transplanting technology has developed rapidly, and the proportion of mechanized rice planting has risen...
