First, the field management after transplanting
After transplanting rice, due to root injury, the ability to absorb water and fertilizer is reduced, the upper part of the ground stops growing, and the color of the leaves turns yellow until the new roots begin to grow.
(1) Check the seedlings and make up the seedlings. There is often a lack of holes after transplanting. The seedlings must be inspected in time to ensure the proper density and basic seedlings.
(2) Look at the seedling irrigation. After the seedlings are planted, they can fill some water. After two or three days, they will fall to an inch or so. The seedlings are transplanted, and the shallow water is about 1 inch.
(3) Recovering the green fertilizer. When the new root grows 2-3 inches, it can be traced back to the green fertilizer to promote the birth of the new leaves quickly and early. When topdressing, the shallowness is about 1 inch, and about 2 kilograms of ammonium sulfate is applied per mu.
(4) Prevention and control of leaf miner hazards. With rice transplanting, the leaf miner was also transferred from Putian to Daejeon. It can be sprayed with "Happy Fruit" and it works well.
Second, the management of the period
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 the ineffective sputum, and reach the normal "joint yellow" in the highest tillering period, laying the foundation for high yield.
(1) Early application of manure. At the beginning of the tillering period, the application of nitrogen fertilizer to meet the needs of long leaves and long tillers of rice is suitable for applying 2.5 kg of urea per acre, up to 5 kg. Fertilization should not be too late, otherwise it will easily cause the child to fall.
(2) Shallow water pouring and proper drying. 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 have sufficient light and oxygen at the branching node 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 used to drain the field, control the growth, reduce the ineffective sputum, and prevent the lodging.
(3) Control weeds and pests and diseases. Herbicides have been widely used in weed control, which not only eliminates weeds in rice fields, but also reduces a lot of heavy labor. In the tillering stage, pests and diseases must be controlled, mainly rice blast, seedling disease, brown spot, and bacterial blight. Insect pests such as stem borer, rice locust, and rice leaf roller. It should be checked in time and prevented in time.
Third, long-term management
The growth of rice during this period is characterized by vegetative growth and reproductive growth. In addition to the sharp growth of stems, the young panicles rapidly differentiate and form, and the tillers are transformed into two poles, which effectively continue to grow and develop. Ineffective mites gradually die, and rice fields prevent premature closure. To ensure that the young ears are well differentiated.
(1) Skillfully applying the long-eared fertilizer. Any leaf-yellow-deficient field after jointing should be applied with panicle fertilizer, which has a significant effect on consolidating effective tillers and increasing the number of grains per panicle. Generally, about 2.5-5 kg ​​of urea is applied. Do not apply too much fertilizer, so as not to cause adverse consequences. Booting is generally no longer topdressing, such as the yellowing of stems and leaves at the end of the booting stage, showing premature aging, and can be applied to the fertilizer 15 to 18 days before the earing. Generally, 1 to 2 kg of urea is applied per mu. Do not allow too much fertilizer to cause gluttony and late maturity.
(2) Filling in the "fostering tires" water, and drying the fields in due course. The panicle differentiation stage of rice is the period of rapid growth and water demand in rice during the whole life, and it is the weakest period of drought tolerance and cold tolerance. If water is scarce, the young ear is affected first, which not only affects the normal development of pollen grains, but also affects the transportation of nutrients to the ear. It is easy to cause short ears, few grains, and many empty shells. At this time, it is in the midsummer, the sun is strong, the temperature is high, and the water layer can be properly deepened to control the water temperature. Generally keep the water layer 2-3 inches deep.
(3) Prevention and control of pests and diseases. After rice jointing, the epidemic of pests and diseases, sheath blight, bacterial blight, leaf blast, and stem borer, rice leaf roller, rice borer, etc. are often harmful during this period, and attention should be paid to timely treatment.
Fourth, the management of the solid period
The general principle of rice management in this period is: rooting and leaf protection, preventing premature senescence of leaves, promoting grain fullness and preventing empty shells.
(1) Reasonable irrigation and timely drainage. During the flowering and blooming, the field still needs to maintain a certain water layer, adjust the water temperature, increase the air humidity, and facilitate flowering and pollination. In the filling period, dry and wet and wet, mainly wet, the method of irrigation, that is, after pouring water, naturally dry for l or 2 days, and then once again water. This can achieve the purpose of nourishing the roots with water and protecting the leaves with water, which is conducive to promoting the filling and preventing premature aging. Into the wax maturity period, it is necessary to adopt dry and wet and wet, dry-based irrigation method, naturally drain for 3-4 days after pouring water, and then watering. Later, the water is drained 7-10 days before harvest.
(2) Harvest at the right time. Rice harvesting is generally from the late waxy stage to the early stage of ripening. At this time, the grain turns yellow, and the stems, leaves and ears turn yellow. It should be harvested in time to ensure the harvest and harvest
