At present, the province's rice has entered the transplanting stage one after another. As a result of continuous drought, some rice fields in the field are under tight water supply, which has a certain influence on rice transplanting in proper period. All localities must actively open up water sources for drought and strengthen the management and dispatch of farmland water sources to ensure that rice is planted in a proper period. At the same time, according to different types of rice cultivation guidance, do a good job transplanting rice and a work on the tube.

1. Strengthen the scheduling of water sources, ensure timely transplanting, actively open up water sources, strengthen the management and scheduling of irrigation water sources, organize irrigation machinery in a unified manner, make full use of rivers, lakes and groundwater, and alleviate the problem of inadequate storage capacity of reservoirs. For well-distributed fields, promptly fill up wells to prepare for timely water supply in severe drought seasons. At the same time, we must strengthen the clean-up and restoration of the existing water mains, and do a good job in membrane leakage prevention and leakage prevention. Actively implement the water supply for small and medium-sized reservoirs, emergency dredge of drainage channels, clean-up and repair of large-pits and dams, start of hydropower station round-robin irrigation and water-lift irrigation, and other measures to ensure normal water supply for rice transplanting.

2. Organize early ploughing and increase the quality of soil preparation After the summer crops are harvested, catch the fine weather and make full use of mechanical surprises to turn over the stalks. Under this year's special drought conditions, we advocate the application of drought-sprouting technology in paddy fields, improve the quality of land preparation, shorten the time for field soaking, and save water for field use. Straw returned to the field, after the ploughing of Shek Shui Putian to soften the straw, the use of a medium-sized tractor supporting the straw returned to the field one-time burying tillage, so that grass and mud fully mixed, before planting 1 to 2 days Good field, planted after the soil is solid. Daejeon's land preparation is done in fields, mud, and fertilizers. The difference between the fields is no more than 3 cm. The fields are neat and tidy. The topsoil is fine and the top is rotten. For machine-inserted fields, it should be moderately settled after leveling. The sandy soil should be solid for about 1 day. The loam should be immersed for 1 to 2 days. The clay should be immersed for 2 to 3 days until the mud is precipitated and the topsoil is planted with moderate hardness. .

3. Adjusting the age and elasticity of crops, and increasing the quality of planting The tight water supply in farmland may lead to excessive planting of rice in some areas, which is not conducive to early emergence of seedlings and ear protection. The flexibility of ageing should be adjusted in time and the quality of planting should be improved in accordance with the situation of the estuary linking and Datian water supply. In particular, machine-inserted rice and cast-or-transplanted rice, which cannot be transplanted on time, are required to delay the fertility process through dry tubes and appropriate amounts of growth auxiliaries such as paclobutrazol, and reduce the proportion of super-soil seedlings. Machine-planting transplants are generally transplanted at the 3 to 4 leaf stage, and the seedlings are kept at 15 to 20 days. The conventional hand-planted seedlings are transplanted at the 6-leaf stage, and the seedlings are controlled at about 30 days. The cast seedlings are generally thrown at the 4 to 5 leaf stage. Planting, age control in 20 to 25 days. Machine inserted rice generally planted between 18,000 to 20,000 holes per acre, about 4 seedlings per hole, about 70,000 to 80,000 per acre basic seedlings. Hand-planted conventional japonica rice row spacing 25 cm, plant spacing 13 cm, basic stem seedlings per mu of 90,000 to 100,000; high yield side, high yield field spacing 26 to 27 cm, spacing 13 cm, basic stem seedlings per acre 80,000 to 9 Million. Hand-planted hybrid rice spacing 28 to 29 centimeters, basic stems and seedlings per mu of 70,000 to 90,000; high-yield, high-yielding fields are about 29 cm, the basic stem and seedlings per mu more than 70,000. Throwing rice generally requires seedlings to be set (40 retort trays for 561 holes and 434 holes for platters per hectare), with 18,000 to 20,000 holes per acre, and more than 70,000 seedlings per acre. Shallow water high throw, even throw. The basic seedlings can be reasonably adjusted according to the planting period and the characteristics of the tiller of the cultivar. The basic seedlings of the cultivars with appropriate transplanting and strong tillering characteristics can be appropriately reduced, and the seedlings with delayed transplanting and poor tillering characteristics should be increased accordingly.

4. Strengthen field management and promote the early emergence of seedlings. According to the planting methods and field conditions, due to seedling management, classification management, and a good grasp of the work of management. Water slurry management, transplanting rice to promote early-onset and strong seedlings as the goal, from transplanting to a new leaf returning to the green period to irrigate seedlings, water depth of about 3 cm; shallow water in the tillering period ground irrigation, water to gas, with The water is used to regulate fertilizers to promote multiple rooting and delivery. Straw returned to the field, so that short-term dehydration, open field, increase the amount of oxygen in the soil, promote straw maturity, to prevent the soil toxic substances caused by too much stiff seedlings. In areas where there is a shortage of farmland water supply, the use of water-saving irrigation technology is strongly promoted. Fertilizer management, transplanting rice to do live tree after early application of fertilizer, the general requirements of hand-planted rice, throwing rice in the 5 to 7 days after transplanting planting, urea per acre of about 10 kilograms; , Adhere to the split application, generally about 5 days after planting urea 5 ~ 6 kg per mu, about 12 days after planting 10 kg of urea per acre. For deficiencies in the base fertilizer, 7 days after the application of fertilizer to see the balance of the balance of fertilizer applied, usually 3-5 tons of urea per acre. In areas where there is a shortage of farmland water supply, the combination of farmyard manure and phosphorus and potassium fertilizers will be used to improve soil water storage and fertility and rice's own drought resistance. In addition, drought will aggravate the occurrence of pests and weeds, and prevention and control should be strengthened, especially for the prevention and control of major diseases and pests such as rice stripe disease and black-streaked dwarf disease and chemical weeding in the field. For the delay in transplanting, the quality of the seedlings will decline, and the emergence of sterile seedlings should be based on specific circumstances, should take appropriate fertilizer, medicine, water management and control measures to enable the seedlings to resume growth as soon as possible.
