No-tillage of rice - the technical essentials of no-tillage treatment
1. Early rice mid-season no-tillage treatment. Use the biocidal systemic herbicide to apply the medicine 10-15 days before throwing, use 150-200 grams of “Pangkor 747â€, and use the contact-type broad-spectrum herbicide to apply the drug 7 days before throwing. The use of 200-250 grams of 20% gram of acre is mainly used to prevent weeds in rice fields and fields. Within one week before spraying, keep the field with a thin layer of water, which is conducive to weed germination and soil softening. When applying, the field should drain the water and try to choose sunny days. According to the above dosage, add 4 kg of ammonium carbonate to 60 kg of water, and evenly spray the weeds in the field and field, pay attention to not leaking. 2-5 days after application, return to the water in full, soak the rice fields for 7-10 days, and wait until the water layer is naturally dried or drained. If the season allows, the dipping time is longer and the effect is better.
2. Late rice no-tillage treatment. It is not advisable to prematurely break water before harvesting in early rice to keep the soil soft; it is not suitable for over-harvesting when harvesting, and it is suitable to maintain the fresh greenness of the base rice pile; the harvest should be as low as possible, the height of the rice pile should not exceed 15 cm, to 10 Below the centimeter is appropriate. Avoid the adhesion of the field mud to the rice piles during the early rice harvesting. After harvesting, drain the field water. In the evening, use 20% gram of 200-250 grams of ammonium carbonate and 4 kg of ammonium carbonate, and wash 60 kg of water, evenly spray each. Rice piles and weeds in the fields and fields. One day after the application, the rice fields were fully returned to the water, and the rice fields were soaked for 2-4 days. After the water layer was naturally dried or drained, the rice was thrown. In the no-tillage paddy fields where the season is very tight, the shallow water can be thrown into the pond one day after the backwater immersion in the field, but this method should be carried out carefully according to the specific conditions.
Before throwing in the raft, if you find that the field is too deep and too deep, you can use the farmer's shovel to simply flatten it without ploughing. After draining the shallow water, you can throw it.
The no-tillage paddy soil is not as soft as the traditional plough. The weeds and early rice cultivars may not have completely rotted when throwing mites, but it will not affect the normal growth of rice.
