1. To cultivate age-appropriate drought-strength ploughs: fertilize the seedbed, apply strong hoeing agents, plant seeds at appropriate time, dry up the dry tube, cultivate the strong maggots, transplant the medium and small seedlings with soil (age 4-5.5 leaves). It is critical to cultivate age-appropriate and strong (preferably drought-fed larvae). This technology adopts moist cultivation. The seedlings are not strong and the seedling stage is obvious, and it is easy to invert the seedlings and dead seedlings and affect the yield increase and efficiency.
2, the whole field fertilization: first plowing ploughing fields, do Tianping mudification. Before fertilization, one-time application of chemical fertilizer (organic fertilizer should be applied one month before transplanting). After spraying the fields, press 2m wide and the surface is smooth, with a width of 30cm, a depth of 20-30cm, and a good ditch. The amount of nitrogen fertilizer is generally only 70-80% of the amount of local applied fertilizer. The amount of nitrogen used in arid regions is slightly higher. Phosphorus and potassium fertilizers are generally superphosphate 30-40kg/mu. 3, film: choose a width of 2m, thickness 0.005 -0.008mm micro-film, plaster mud, film and soil interface no gaps, in order to facilitate the separation of oxygen and weeding, mud around the membrane 3 - 5cm, to prevent the wind unveiled film.
4, standard transplanting: pull the film broken transplanting, broken with a wooden stick film, can also be broken in accordance with the specifications on the wooden bar broken wooden stick broken film, pay attention to the film hole should not be too large, or affect the film coating effect. The implementation of honeycomb planting, row spacing is 26cm, plant spacing 16cm, acres planted 15,000 bundles, 2-3 plants per cluster, the basic seedlings per acre 3-45 million seedlings.
5. Daejeon Management: After the transplanting, the whole process of dry management shall be implemented. Under normal circumstances, as long as the water in the ditch is maintained, the water is not on the surface of the ditch. In areas with more rain, it is not necessary to water the ditch. Pay attention to the drainage in each growth period and try not to submerge. Water ripples. In the booting stage and heading stage, 1-2 horse-racing waters are irrigated as appropriate. If defermentation occurs later, extra-root fertilizer may be applied 1-2 times, such as spraying nitrogen, phosphorus, potash, or growth regulators, or using “running horse waterâ€. Way to apply urea 2 -4kg/mu.
6. Prevention and control of diseases, pests and rodents: The use of weeding rice for filming of dry-land rice does not require weeding. However, management of pests and rodents should be strengthened in the management of mid- and late-stage diseases.
7, timely harvest, rice piles should not be high should be short, it is beneficial to remove waste film.
