Rice transplanting precautions Be careful: do "four bogey" when transplanting 1. Avoid inserting overnight: The nutrient consumption of the seedlings is large, the resistance is reduced, and the greening is slow. 2. The transplanting is too deep: 1-2 cm is appropriate, too deep and low, the number of branches is reduced, the number of panicles is reduced, and the yield is affected. The depth of insertion is less than 1 cm, although the ear is large and the ear is small, it is not resistant to lodging; the depth of insertion is more than 2 cm, and the ear is small and cannot be high-yield. 3. Avoid inserting the field water too deep: the water depth is low, and the sputum is early and suffocating. Jinfeng Tianyi presents the phenomenon of drifting seedlings. 4. Avoid transplanting too early and too late: May 15 to 25 is the high-yield transplanting period of rice. Too early and late have an impact on production. Rice transplanting standards to comply with 1. After the water is transplanted into the water (about 1 cm in water depth), the seedlings should be released in time, and the water depth is 2/3 of the height of the seedlings. Protect the seedlings with water, and promote the early return of the seedlings to the early morning tillers by increasing the temperature of the water. 2, to ensure that when the early arrest, reasonable close planting, to ensure the basic number of seedlings in the field. It is recommended that the insertion standard is 9X4, 25-33 holes per square meter, and the production requirements of 5-6 plants per hole are ready for high yield. Plants are too dense to affect ventilation and light transmission, easy to fall and reduce production; too thin, although ventilation and light transmission, strong resistance to lodging, but the number of spikes in the field does not meet the high yield requirements, but also affects the output. 3, the depth of the transplanting should be regular and common, not high and low. Planting a special person to fill the seedlings together to ensure the number of seedlings in the field. 4. When transplanting, it is necessary to determine whether the mud accumulation is in compliance with the standard. That is, the surface of the field is gradually closed with fingers. Fingers can not be grooved, and the accumulation is not good, which will constitute a silt phenomenon, affecting the return to green. The finger does not sag, the accumulation is excessive, the machine injury is severe and the same effect affects the green. After transplanting rice, it usually turns from green to yellow, and then turns from yellow to green. This time is called the regreening machine. The seedlings are green and the four leaves are born. Therefore, it is also called the green leaf. The leaf length is 11cm and the plant height is about 17cm. The number of stems should have 10% of the 1 leaf splitting tip. How to decide whether to return to green? After transplanting, 50% of the plant's heart leaves are turned over at noon on sunny days, or the new leaves are sprinkled with water at the tip of the leaf. Early return to the strengths of youth? Returning to Qingqing for 1 day, the accumulated temperature of the accumulated temperature above 20 °C during the robust period is conducive to the safe heading of rice. Processing technology critical? Immediately after returning to green, the green fertilizer is applied, so that the fertilizer effect is in the leaf position of the Shengyu (6 leaves). If the fertilizer is applied twice, the second fertilizer is applied before the 6th leaf stage to prevent the fertilizer effect from being effectively distributed. After the critical leaf position. During the tillering period, you should pay attention to the clearing of the application, shallow water fertilizer, try to make the soil and fertilizer mix, to advance the fertilizer effect, do not fill the irrigation after about one week after the fertilizer, cut the loss of nutrients.
