The "small full" solar terms, the farmer's squatting "small rushing to the valley full of autumn." At this time, the middle rice in southern Sichuan has been fully planted. How should rice fields be managed? Recently, the author visited Dai Bin, the stationmaster of the Agricultural Technology Station of Huguo Town, Naxi District, Ganzhou City. He introduced some technical points of rice field management:
Field tube after transplanting
  After transplanting rice, due to root injury, the ability to absorb water and fertilizer is reduced, the aboveground part stops growing, and the leaf color turns yellow until the new roots begin to grow.
  Check seedlings and make up the seedlings. After transplanting, there is often a phenomenon of lack of acupoints. It is necessary to check the seedlings in time to ensure the proper density and basic seedlings.
  Look at the seedling irrigation. After transplanting the seedlings, some water can be deepened. After two or three days, the plants are shallow to about 1 inch; the seedlings are transplanted and the shallow water is about 1 inch.
  Recovering the green fertilizer. Dry nursery will return to green quickly, and water breeding will return to green. When new roots grow out, they can be traced back to green fertilizer to promote the birth of new leaves quickly and early. When topdressing, the shallow water is about 1 inch, and the urea (or ammonium bicarbonate) is about 2 kg per mu .
  Control the damage of leaf miner. With rice transplanting, the leaf miner was also transferred from Putian to Daejeon. It can be sprayed with "Happy Fruit" and it works well.
Club time management
The tillering stage of rice is mainly long root, long leaf and long tiller vegetative, which is the main period of vegetative growth and is the key period for determining the number of panicles. Management tasks: It is necessary to promote the rapid development of early birth, increase the effective sputum, control invalidation, and reach the normal "joint yellow" in the highest tillering period, laying a foundation for high yield.
  Early application of manure. In the beginning of tillering, nitrogen fertilizer, rice leaf to meet long, long tiller, 2 urea per acre. 5 kg is suitable, up to 5 kg. Fertilization should not be too late, otherwise it will easily cause the child to fall.
  Shallow water pouring, appropriate drying field. During the tillering period, especially during the effective tillering period, rice is generally watered for about 1 inch, which can increase the temperature of the ground temperature and water, promote the decomposition of soil nutrients, and provide sufficient light and oxygen at the tiller joints to promote the occurrence and growth of tillers. Saline-alkali land should be irrigated with live water to prevent deterioration of water quality and damage rice seedlings. When the effective tillering period is over, deep water is required to inhibit the occurrence of tillers. When the growth is too strong, it can be combined with drainage to control the growth, reduce the ineffectiveness, and prevent the lodging.
  Weeding should use herbicides reasonably, not only can eliminate weeds in rice fields, but also reduce a lot of heavy labor. In the tillering stage, pests and diseases must be controlled, mainly including rice blast, seedling disease, brown spot, bacterial blight and sheath blight. Insect pests such as stem borer, rice locust, and rice leaf roller. It should be checked in time and prevented in time.
