Embodiment 1

[0030] A kind of seedling cultivation method, comprises the following steps:

[0031] (1) Carry out multiple intermittent clear water soaking and intermittent disinfection soaking to the seeds until they break and germinate, wherein the intermittent clear water soaking and intermittent disinfection soaking are carried out under an oxygen-enriched environment, and the intermittent clear water soaking is first soaking the seeds in clear water 8h, then take out the seeds and let stand for 2h, then soak the seeds in clear water for 8h, the intermittent disinfection soaking is to first soak the seeds in sterilized water for 8h, then take out the seeds and let stand for 2h , the seeds are soaked in sterilized water for 8 hours, the concentration of the sterilized water is 0.15%, and its component is prochloraz;

[0032] (2) sow the seeds in the seedling raising field, raise the seedlings for 20 days, and get the seedlings, wherein the seedling raising field is set under an oxygen-en...

Embodiment 2

[0053] This embodiment is basically the same as Embodiment 1, the differences are as follows.

[0054] A kind of seedling cultivation method, comprises the following steps:

[0055](1) Intermittent seed soaking in clear water and intermittent disinfection soaking are carried out to the seeds until they germinate. The intermittent seed soaking is carried out in an oxygen-enriched environment, and the intermittent seed soaking is to first soak the seeds in clear water for 10 hours, and then take them out The seeds were left to stand for 5 hours, and then soaked in clear water for 10 hours. The intermittent disinfection and seed soaking was to first soak the seeds in sterile water for 10 hours, then take out the seeds and let them stand for 5 hours. Soak in disinfectant water for 10 hours, the concentration of said disinfectant water is 0.2%, and its component is prochloraz;

[0056] (2) sow the seeds in the seedling raising field, raise the seedlings for 20 days, and get the se...

Embodiment 3

[0060] This embodiment is basically the same as Embodiment 1, the differences are as follows.

[0061] A kind of seedling cultivation method, comprises the following steps:

[0062] (1) Intermittent seed soaking in clear water and intermittent disinfection soaking are carried out to the seeds until they germinate. The intermittent seed soaking is carried out in an oxygen-enriched environment, and the intermittent seed soaking is to first soak the seeds in clear water for 10 hours, and then take them out The seeds were left to stand for 3 hours, and then soaked in clear water for 10 hours. The intermittent disinfection and seed soaking was to first soak the seeds in sterile water for 8 hours, then take out the seeds and let them stand for 2 hours. Soak in sterilized water for 8 hours, the concentration of said sterilized water is 0.2%, and its component is prochloraz;

Abstract

The invention discloses a seedling cultivation method. The method comprises the following steps: (1) performing intermittent clean water seed soaking and intermittent disinfection seed soaking on seeds until the seeds break and germinate; (2) sowing the seeds in a seedling raising field, and raising seedlings for 18-25 days to obtain seedlings; (3) strengthening the seedlings, transplanting the seedlings into a field parcel, and plowing, fertilizing and disinfecting the field parcel 10-30 days before transplanting; (4) in 5-20 days after transplanting, weeding the field parcel and applying tillering fertilizer to the field parcel so as to obtain strong seedlings. In the prior art, seeds are polluted again after being exposed to the air for a long time; the seeds are soaked intermittently in the invention, so the time that the seeds to exposed to the air at a time can be greatly shortened, and disinfection effect is better; the seeds are sown to the seedling raising field, then seedlings are strengthened, and the strengthened seedlings are transplanted to a field piece, so yield can be increased.

Description

technical field [0001] The invention relates to the technical field of japonica rice cultivation, in particular to a seedling cultivation method. Background technique [0002] Japonica rice is a subspecies of rice. It needs short sunshine time, but has a long growth period. It is relatively cold-resistant, has strong stickiness, short and round grains, high protein content and good taste. [0003] Japonica rice is resistant to fertilizer and lodging, and has high water management requirements. It should be planted in plain areas with deep soil, good soil foundation, and convenient drainage and irrigation. During the planting process of japonica rice, the seeds are first sterilized, then placed in the air to make them germinate, and then the seeds are directly sown in the fields. [0004] In the existing japonica rice planting process, disinfection and germination are carried out separately, the efficiency is poor, the disinfection effect is poor, and the seeds are directly ...
