Northeast rice area must strengthen management of paddy fields

Science transplanting. Reasonably determine the transplanting density and avoid super-diffusion. According to the quality of seedlings, strong seedlings should be thin and weak seedlings must be denser; soil fertility levels should be higher, and lower levels should be denser. The range of motion is: the number of basic seedlings is 100-120 seedlings/square meter, and the number of seedlings is 25-30 points/square meter. The machine insertion depth is preferably 2 cm, and the deepest depth should not exceed 3 cm. The artificial hand is inserted or planted and the depth is about 2 cm. If it cannot be planted in time, "paclobutrazol" may be used to appropriately extend the age of the plant.

Rational fertilization. For Honda's fertilization, it is necessary to apply less and reasonable nitrogen fertilizer, increase manure, reduce fertilizer, and prohibit the use of nitrate nitrogen fertilizer. Promote the use of rice special package fertilizer. The ratio of nitrogen, phosphorus, and potassium is 1:0.5:0.7 in order to achieve balanced fertilization. The base fertilizer is 350-400 kg of special fertilizer for rice per hectare, which is applied in one-time combination with the water preparation site to achieve full-layer fertilization. For Honda Topdressing, after transplanting, use 130-150 kg of special returning green manure per hectare, add 30 kg of biological fertilizer, mix and mix evenly, and apply it at the same time. Around July 10, 150-200 kg of panicle fertilizer was applied per hectare of rice. At the same time, at the tillering, booting, and filling stages, the growth of rice is sprayed with foliar fertilizers such as amino acids or humic acids. The last top dressing must be done 30 days before harvest.

Reasonably irrigated. After transplanting, the seedlings will be returned with 2/3 of the water before seedlings and seedlings will be nursed. The effective tilling period will be filled with shallow water of 3cm to increase the temperature and promote the growth. The field will be drained 3-5 days before the end of effective tillering. The sun cracked the ground and the ground saw white roots. The leaves were light and tinted. The sun returned to normal water after 5-7 days. The panicles were filled with 4-6 cm of water before heading. During the meiosis (mid-to-late July), encounter 17 °C low temperature, irrigation more than 15 cm deep water tire protection, immediately after the low temperature to restore the original water level; heading flowering period, irrigation 5-7 centimeters of water, grouting to wax maturation intermittent irrigation, Wet and dry, mainly wet, cut off water about 7 days before harvest.

Prevent disease. Before the transplanting, a centralized prevention and control was conducted at the seedbeds, which mainly aimed at leafminers and rice blasts, which could reduce the use of drugs, improve the control efficiency, and reduce the incidence of insects in Honda. Put 10-15 grams of 10% imidacloprid per 100 square meters of seedbed 1 day before transplanting, 15 kg of water, mix with 20% tricyclazole wettable powder or 30% rice bran (Fuji No. 1) EC.

Especially for rice blast, the control of leafhoppers should be sprayed 1-2 times in the middle and later stages of the tillering period. The control of the panicle blast can be sprayed once during the rice breakage period to the heading stage, combined with weather conditions, at the heading stage of rice. Spray once. When spraying, choose sunny and early morning and evening without wind or breeze. In the application of pharmaceuticals, chemical pesticides can be used alone, and chemical pesticides and biological pesticides can also be mixed: 20% or 75% of tricyclazole wettability Powder is a special fungicide for rice blast, in addition, 40% of Fuji No. 1 WP, 40% of Kesongsan EC, 50% of carbendazim WP, 25% of SP, 2% of NS wettable powder Or 2% of kasugamycin wettable powder + 50% carbendazim WP, 25% SPK EC + 2% kasugamycin wettable powder, etc. have good control effect.

Weed control. After the transplanting, the grass is closed for the first time after soil preparation, and the herbicides with high safety and good control effect are selected: arogens, phenthramine, sun stars, bentazone, oxadiazone, etc. Or cast rejection method, the water layer 3-5 cm, water retention 5-7 days. At the 5.5 leaf stage of rice, the second herbicide was performed according to the seedlings and the grass condition. The leaf age of the grass was before the leaf stage of 1.5 leaf days - phenicillin; and the grass was before the 2.1 leaf leaf stage - arogin. At the same time with broadleaf herbicides such as sun stars, etc. mixed with toxic soil or spray method. In the late 6-leaf stage of rice, the prevention and treatment of late-old rice bran is carried out: When 3-4 leaves of rice bran are used, a dose of 100 ml per acre is used, and when a rice bran is used for 4-5, 120 ml per acre is used.
