Remember to do a good job of dry cultivation of rice at 13:00
The technology of diskless rice seedling throwing in dry cultivation is a light and cost-saving cultivation technique of rice, which adopts special medicine fertilizer and slow-release super absorbent seed coating agent "dry nursery nanny" to coat rice seeds, raise seedlings in dry condition, and directly throw seedlings in the field after pulling seedlings. The key points of cultivation techniques are as follows:
First, choose the right model. In the application of dry cultivation and seedling throwing, the "dry nursery nanny" of seedling throwing type should be selected.
Second, determine the dosage. Each bag (350g) "dry nursery nanny" super absorbent seed coating agent coated rice seed 1kg-1.5kg.
Third, soak the seeds. The selected rice seeds were soaked in clear water for 12 hours for 24 hours, the soaking time was long when the temperature was low, and the time was short when the temperature was high.
Fourth, the method of coating. Remove the soaked rice seeds and drain them until they are not dripping. According to the proportion of 1 kg to 1.5 kg of rice seeds coated by each bag of "dry nursery nannies", the seeds were mixed and all the seed coating agents were wrapped on the seeds.
Fifth, choose a good seedling site, apply sufficient basic fertilizer, and straighten out the seedling compartment. Select loam fields (or soil fields) and fields with less fertile weeds as seedling fields.
Sixth, pour enough bottom water. The bottom water of the dry seedling bed should be poured thoroughly, so that the water content of the 0-10 cm soil layer of the seedling bed can reach a saturated state.
Evenly sowing and covering seeds. Sow the wrapped seeds evenly in time and cover a thin layer of fine soil 2cm to 3cm thick after being slightly shielded.
Eighth, spraying special herbicides for dry nursery seedling fields, such as dry seedling green and so on.
9. The seedling bed needs to be watered once in the afternoon before throwing and pulling seedlings, so that there is a "moisture-absorbing mud ball" at the root of the seedlings to facilitate the establishment of seedlings. It usually takes one or two seedlings to be pulled up.
The method of dry cultivation and seedling throwing, field management and pest control are the same as those of conventional plastic tray seedling throwing.
11. The amount of hybrid rice used in the field is about 1.5kg per mu, and the ratio of seedling field to field is 1 ∶ 12: 15.
12. Determine whether to cover the film or not according to the air temperature after raising seedlings and sowing. Cover the film for heat preservation and moisturizing when the temperature is low.
13. Irrigation is strictly prohibited within two days after throwing seedlings.

Four passes to control rice sheath blight
In recent years, sheath blight has become the most important disease of rice, and has four major characteristics: first, a wide range of occurrence. Second, there are very few varieties resistant to sheath blight. Third, the harm is becoming more and more serious, even causing lodging through the top. Fourth, the disease is first caused by the lower part of the rice plant, which is easy to ignore and miss the favorable opportunity for prevention and control. It is the key to strictly control the four hurdles in the prevention and control strategy. 1. Salvage sclerotia sheath blight mainly overwinters in rice fields in the form of sclerotia. When overwintering sclerotia pass through winter and spring to early rice transplanting, 60% to 70% of sclerotia can germinate. Most of the sclerotia are lighter than water and longer.

Remedial measures for waterlogged crops Rice
Rice has a strong tolerance to waterlogging, with no top for about 3 days, and there are still about 80% of the surviving rice seedlings, as long as the management is strengthened; if the rice seedlings are not topped for 4-7 days, 50%-80% of the survived rice seedlings should be homogenized and replenished in time to ensure a sufficient population; if there are only about 30% of the surviving rice seedlings without the top for more than 7 days, replanting or replanting other crops should be considered. It is necessary to take measures in accordance with local conditions, give classified guidance, and conscientiously do a good job in the post-disaster management of rice. As long as there are green leaves in the rice seedlings, the inside of the leaf sheath is still green and has a certain hardness, white roots or roots are light yellow, and the water is 2 ~.
