Rice Honda Management Technical Key Points
1, Feifei: The split manure is applied twice. The first time tiller fertilizer is applied 50% of the total amount of manure immediately after returning green, and no later than 6 leaf stage (before June 10th), to promote early delivery of delivery and use low tiller; when the end of 7th paddy rice to the first 8 when the leaves are exposed (depending on the species, generally on June 17-20), use the remaining manure for fertilizer application, that is, the second manure. 2. Panicle fertilizer: In the 10-leaf stage, young panicles begin to differentiate and begin to use panicle fertilizer. The panicle fertilizer was applied twice. The first time when the third leaf was just exposed (before and after July 5) 60% of the total amount of panicle fertilizer promoted the differentiation of spikes, branches, one spikelet number, increased the number of primary branches, and strived for large spikes; The second time, when the flag leaf (falling 1 leaf) was exposed (July 18-20), it was irrigated with 3 water-savings using the remaining panicle fertilizer. Water management should meet the requirements for promoting fertility, such as “strengthening roots, warming, ventilation, and water conservationâ€. (1) Shallow water promotion: When transplanting, keep the flowers in the pool up to a maximum of 2/3 of the seedling height in the water layer after transplanting, turn the seedlings back to green, and return to green, keep the water layer 3.3 centimeters, and increase the temperature to promote flooding. After 10 leaf stage, dry, wet, wet irrigation was used. Increase the amount of oxygen in the soil and promote lower roots. Until 40 days before heading; (2) Roasting field strong stalks attack large spikes: When the number of stems in the field reaches 80% of the planned number of stems (from June 28 to July 8), it is necessary to overwhelm the growth. There are patches of closed vegetation, dark leaves, fallen leaves, and no jointing yellow. Spread the water for 7-10 days. Instead, dry the soil instead. The degree of drying in the fields is whitish, cracked on the ground, white roots on the surface of the pool, faded and straightened leaves, and the control promotes the promotion of strong stalks; (3) deep-water tire protection and shallow water grouting. Rice meiosis is the period most sensitive to low temperature in rice. To prevent cold damage, when the temperature is below 17°C, 15 cm deep water layer is used to protect the baby. In the rest of the time, intermittent wet and dry-wet intermittent irrigation should be adopted to raise the roots and keep the leaves mature. Irrigate 4 to 5 centimeters each time and let it dry naturally before filling. Yellow mature period of water.
