Problems solved by technology

Seedling raising on hard ground is usually carried out on vacant concrete ground, and the suitable period is generally in the middle and late May. If the temperature in May is high, the temperature of the cement field will increase, and the rice seedlings will grow rapidly, which will easily lead to excessive growth and excessive growth of the seedlings.
Seedlings that are too tall and too tender are not conducive to grasping seedlings with claws. The damage to the seedlings is serious, and the planting injury after planting is large. The slow seedling period is long, which is not conducive to early seedling emergence, which has a certain impact on the stable and high yield of rice.
[0003] At present, there is no soaking method that can effectively control the vigorous growth of rice seedlings raised on hard ground

Embodiment 1

[0019] (1) The rice seeds are dried in the sun for 1 day, and the empty seeds, shriveled seeds and weed seeds are removed to ensure that the seeds are even and full, and the branches (or awns) are debranched (or awned);

[0020] (2) clear water cleans seed, then packs in mesh bag, and the amount that rice seed is housed in each mesh bag is 18kg;

[0021] (3) 17% fungus clear solution and 15% paclobutrazol solution are mixed, diluted with water, and the mesh bag with seeds is completely soaked in the diluted solution, the 17% fungus clear solution, 15% paclobutrazol solution, water The weight ratio to the seeds is 15:0.8:6000:4500, and the soaking time is 68h;

[0022] (4) Take out the soaked seeds, dry them naturally, and sow them.

Embodiment 2

[0024] (1) The rice seeds are dried in the sun for 2 days, and the empty seeds, shriveled seeds and weed seeds are removed to ensure that the seeds are even and full, and the branches (or awns) are debranched (or awned) for those with branches (or awns);

[0025] (2) clear water cleans seed, then packs in mesh bag, and the amount that rice seed is housed in each mesh bag is 22kg;

[0026] (3) 17% fungus clear solution and 15% paclobutrazol solution are mixed, diluted with water, and the mesh bag with seeds is completely soaked in the diluted solution, the 17% fungus clear solution, 15% paclobutrazol solution, water The weight ratio to the seeds is 15:1.2:6000:5500, and the soaking time is 76h;

[0027] (4) Take out the soaked seeds, dry them naturally, and sow them.

Embodiment 3

[0029] (1) The rice seeds are dried in the sun for 1 day, and the empty seeds, shriveled seeds and weed seeds are removed to ensure that the seeds are even and full, and the branches (or awns) are debranched (or awned);

[0030] (2) clear water cleans seed, then packs in mesh bag, and the amount that rice seed is housed in each mesh bag is 20kg;

[0031] (3) 17% fungus clear solution and 15% paclobutrazol solution are mixed, diluted with water, and the mesh bag with seeds is completely soaked in the diluted solution, the 17% fungus clear solution, 15% paclobutrazol solution, water The weight ratio to the seeds is 15:1:6000:5000, and the soaking time is 72h;

[0032] (4) Take out the soaked seeds, dry them naturally, and sow them.

Abstract

The invention discloses a seed soaking method for controlling vigorous growth of rice seedlings raised in hardpan of a hard land. The method mainly comprises the following steps: (1) airing rice seeds for 1-2 days and winnowing; (2) cleaning the seeds with clean water and bagging into a net bag; (3) mixing 17% of a germ and worm cleaning solution and 15% of a paclobutrazol solution, diluting with water, soaking the net bag filled with the seeds into the diluted solution; and (4) taking the soaked seeds out, airing naturally, and sowing. Compared with the prior art, the seedlings obtained by the seek soaking method have dwarf single plants and more white roots, grow healthily, have a short recovery period and are quick in sprouting, and thus the high yield of rice can be guaranteed.

Description

technical field [0001] The invention relates to a seed soaking method for controlling vigorous growth of rice seedlings raised on hard ground and belongs to the field of agriculture. Background technique [0002] Hard-disk seedling raising technology transfers the machine-transplanted rice seedling raising and management process to hard ground, making machine-transplanted rice seedling raising truly a thing that can be done with leather shoes. Seedling raising on hard ground is usually carried out on vacant concrete ground, and the suitable period is generally in the middle and late May. If the temperature in May is high, the temperature of the cement field will increase, and the rice seedlings will grow rapidly, which will easily lead to excessive growth and excessive growth of the seedlings. The seedlings are too tall and too tender, which is not conducive to the grasping of the seedling claws. The damage to the seedlings is serious, and the planting injury after planting ...
