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) Dry the rice seeds in the sun for 1 day to remove empty, shattered and weed seeds to ensure that the seeds are even and full, and treat the stalks (or awns) with stalks (or awns);

[0020] (2) Wash the seeds with clean water, and then put them into net bags. Each net bag contains 18kg of rice seeds;

[0021] (3) Mix the 17% Junchongqing solution and 15% Paclobutrazol solution, dilute with water, and completely soak the mesh bag with seeds in the diluted solution. The 17% Junchongqing 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) Dry the rice seeds in the sun for 2 days, remove empty grains, shattered grains and weed grains to ensure that the seeds are even and full, and treat the stalks (or awns) with stalks (or awns);

[0025] (2) Wash the seeds with clean water, and then put them into net bags. Each net bag contains 22kg of rice seeds;

[0026] (3) Mix the 17% Junchongqing solution and 15% Paclobutrazol solution, dilute with water, and completely soak the mesh bag with seeds in the diluted solution. The 17% Junchongqing solution, 15% Paclobutrazol solution, water The weight ratio to the seed 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) Dry the rice seeds in the sun for 1 day to remove empty, shattered and weed seeds to ensure that the seeds are even and full, and treat the stalks (or awns) with stalks (or awns);

[0030] (2) Wash the seeds with clean water, and then put them into net bags. Each net bag contains 20kg of rice seeds;

[0031] (3) Mix the 17% Junchongqing solution and 15% Paclobutrazol solution, dilute with water, and completely soak the mesh bag with seeds in the diluted solution. The 17% Junchongqing solution, 15% Paclobutrazol solution, water The weight ratio to 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 the vigorous growth of rice seedlings on hard-ground hard disk seedlings, and belongs to the field of agriculture. Background technique [0002] Hard-field hard-disk seedling raising technology transfers the machine-transplanted rice seedling raising and management process to the hard ground, making machine-transplanted rice seedling raising truly a thing that can be done in leather shoes. Hard soil seedlings are usually raised on vacant cement ground. The suitable period is generally in the middle and late May. For example, in May, the temperature is high, the temperature of the cement field increases, and the rice seedlings grow rapidly, which can easily lead to excessive growth and lengthening of the seedlings. The seedlings that are too tall and tender are not conducive to the claw grasping of the seedlings. The damage of the seedlings is serious, the planting injury after planting is large,...
