First, the water management has three good points:
1. Put a good quality of DaTian preparations. Early rice dumplings are short-lived and their seedlings are weak, but their roots are well developed.
2. Put a good shot at the Datian water layer. The scientific proposal is to throw water in thin water, but it depends on the weather and the conditions of the water source. In general, the sunny and windless days and the conditions of the poor water source are thrown in water, and the rainy days are cloudy and rainy. Can't throw. Usually about 20,000 holes per mu. In order to make the seedlings evenly planted, take a throw, throw 70% for the first time, throw away the time and shake the seedlings (for profit delivery), throw up (2 to 3 meters high), Then press 3 meters wide and a sidewalk of 20+30 centimeters. The remaining 30% of seedlings will be filled to make sure the seedlings are uniform.
3. Turn off the water after the throw. After throwing, a good level of water will be created. Within 3 to 4 days after throwing, under normal conditions, the field surface will not be watered, and the seedlings will be planted and rooted. After 4 to 5 days after throwing, the field shall be erected and the herbicide should be applied and promoted. Fertilizer, water retention 5-7 days. Afterwards, Asada water was used to promote childbirth. When the number of seedlings reaches 80% of the planned number of panicles, drainage will be put on the field and it is advised to put it on a number of occasions. The maximum seedling control is about 400,000 per mu, not exceeding 500,000. In the middle and late period, dry and wet, intermittent irrigation, enhance root activity and lodging resistance. Timely water cuts to facilitate machine cuts.
Second, apply good fertilizer, in addition to good grass:
1, to apply base fertilizer, generally use 60-70% of the total amount of early rice fertilizer applied to the mouth. The amount of fertilizer to be applied depends on local soil conditions and fertilizer levels. Under general conditions, 25-35 kg of compound fertilizer is applied per acre, 25-30 kg of ammonium bicarbonate, 20 kg of phosphate fertilizer, and 5 kg of potassium fertilizer. Speed ​​up the top dressing, 5 to 7 days after throwing planting, combined application of herbicide Mushi 5.5 kg urea. The panicle fertilizer is a good thing. Potassium fertilizer is the main type. Generally, 5 kg of potash fertilizer is applied to the Mushi. If the growth is poor, apply 4-5 kg ​​of compound fertilizer or 3-5 kg ​​of urea per acre, as appropriate.
2, a reasonable choice of herbicides At present, I am going to throw field weeding mainly selected several herbicides are as follows: 1 Butachlor EC plus azosulfuron-methyl. For every 667 square meters of castor field, 60% butachlor EC 75 ml and 10% pyridine sulfosulfuron (WPK) wettable powder 10 g, 20 kg of fine soil, 7 days after throwing, seedlings take root Shisa. 2 heptyl benzyl (Ainong), benzothiazine, butyl benzyl, dioxobenzyl and other four kinds of compound herbicides. The suitable dosage per 667 square meters is 10% heptylbenzyl 40 grams to 50 grams, 50% benzothiazole 40 grams to 50 grams. 30% butyl benzyl 100 grams to 120 grams, 25% dichlorine total 30 grams to 40 grams. The spraying period was 8 days to 10 days after the seedlings were sprayed (before the 2nd leaf stage of madder). The field was drained first, then the water was sprayed, the field was watered on the 2nd day after spraying, and the shallow water layer was kept for 3 days. ~ 5 days. Its broad spectrum of grasses kills more than 90%. 3 Phenyldanacetamide and benzatholodin compound, or 36% dichloro, benzyl WP (ie fast killing cesareans plus chlorsulfuron), throwing field per 667 square meters dosage of 35 grams to 40 grams . The period of application can be postponed until the waterless layer in the field 10 to 15 days after the spraying. One or two days after spraying, the fields were filled with water and kept in shallow water for 3 days to 5 days. In addition, it is also possible to cast 20% dimethyl tetrachlorohydrin 110 ml and 25% Bentazon water solution 100 ml per 667 square meters and spray 30 kg of water to prevent broad-leaved weeds and sedges. Grass effect is good. 450% of Hydrangea WP. It has special effects on controlling paddy fields and gold. ??
Third, prevent pests
Due to the large number of thrown tussocks and their rapid development, the groups tend to be larger, which easily leads to sheath blight. Therefore, we must pay special attention to the prevention and control of sheath blight. In addition, we must also focus on the prevention and control of insect pests such as stem borers and rice leaffolders.
