Paddy shoot cultivation techniques

Rice throwing bud cultivation is a new form of sowing, and the two technical links of seedling raising and rice transplanting are omitted in the case that the yield is not reduced compared with the transplanting method, which creates a new way of reducing costs, saving labor, and increasing efficiency.
1. Selection of varieties Because this method directly shoots without budding, it is better to select high-yield and disease-resistant varieties when selecting varieties, and the growth period is 10 days earlier than the growth period of the local main varieties. It is necessary to select varieties with compact plant type, dwarf resistance, strong tillering ability, and suitable dense planting, and at the same time, the germination potential is stronger to improve the quality of thrown buds and the survival rate after throwing.
2. The fertilized land is used for the land fertilization. The land surface must be flat, otherwise it will affect the management of the early water. It is convenient for drainage and irrigation, good soil strength, moderate soil infiltration, and no salt and alkali. It is best to turn the floor in order to reduce the number of wild rice. Soil preparation should be achieved by soil preparation, and water should not be exposed. After reaching the level, when applying water, apply 30 kg of N, P, and K fertilizers per 667 m2 (mu) of the base (be careful not to use chemical fertilizers containing chlorine, since chlorine-containing fertilizers will cause serious damage to the milk), and then push the plate once. , And then 0.1 kg Nong Si it herbicides before weeding to close the weeding.
3. The germination can be soaked on May 10th. When the seeds are white, remove the stems, mix the phytodynamics 2003 with 1000 times the water and the same amount of yellow mud, fine sand and small ash into a paste. In a small shed erected with plastic cloth. Stacked to a thickness of 3-4 cm, under the film 10 cm thick straw for germination. Germination temperature does not exceed 30 °C, so as not to grow or burn seedlings. Turn 2-3 times a day and turn it around at noon to make the rice buds uniform.
4. Cast seedlings When the seedlings grow to 2 cm in length, 3-5 roots, and 2-3 cm in length, they can be cast. Before throwing a planter, a 2.5-3 meter wide lattice was inserted with a tether, and 40 cm apart between the lattice and the lattice. The amount of thrown shoots depends on the germination rate and the quality of shoots. Generally, the amount of thrown shoots should be 6 kg per 667 square meters. Note that the length of the seedling shoots is preferably 2 cm. When the shoots are too small, the survival rate is low.
5. Field management water management, milk seedlings in the initial stage of the water layer requirements are more stringent, that is, after throwing planted to the three-leaf until the buds before the time to take moist management, irrigation every 3-4 days waterbed, immediately after the drainage. When the seedlings grow to 4-5 leaves, apply 10% bensulfuron-methyl WP per 667m2, 15g, and 50% henpowder WP to 28g. Mix 15 kg of fluvo-aquic soil and mix well. Weeding. On July 15th, 8 kg of ammonium sulfate was applied for every 667 square meters. Prevent and treat various diseases, pests and weeds in a timely manner, focusing on prevention and control of rice blast and rice smut. At the same time, rice water weevil, clams, and armyworms were promptly controlled.
