Field Management of dry raising Rice seedlings and transplanting in the Field

1. Fine field preparation, so that the field is flat and muddy, and an inch of water does not expose mud. 2. Fertilization principle: heavy application of base fertilizer and skillful application of spike and grain fertilizer. The amount of farm manure per mu is not less than 1500 kg. When raking the field, 70% of phosphorus, potash and nitrogen fertilizer are applied at one time, 20% of nitrogen fertilizer is used as tiller fertilizer, and 10% is used as panicle fertilizer (5 ml 10 days before heading). 3. Adhere to shallow planting, the planting depth is generally no more than 2mi 3cm, the water layer in the field should be as if there is no water when transplanting, irrigate an inch of water about 2 days after planting, and then maintain shallow water management. 4. Planting specifications: early and strong tillers and high panicle rate of dry-raised seedlings. Suitable sparse planting, conventional planting 2.5-35000 clumps, each clump 1 Mel 2 seedlings. Double row strip planting or single row strip planting. However, the reasonable planting density should be determined according to altitude, variety and soil fertility. 5. It is best to use the method of shoveling seedlings with soil, which can also be dry-drawn. If the quality of the nursery bed is poor, the soil is sticky and hardened, and it is difficult to pull the seedlings, they can be watered thoroughly the night before the seedlings are pulled. 6. chemical removal is the same as that of plastic film seedlings. It is best to use butachlor, Acetochlor, Tian Mao, Jindaolong and other herbicides, it is best not to use promethazine. Planting dry seedlings must adhere to the key technical points such as "fertile bed is the foundation, dry cultivation is the center, strong seedlings of the right age is the goal, the field is flat and muddy, shallow planting is the key, and sparse planting is the guarantee". Only in this way can we give full play to the production efficiency in rice production.
