Key points for water management of Zizubai fertilizer

Weeding and plowing 2 to 3 days before transplanting Zuji base fertilization, apply 2500 kg of decomposed organic fertilizer per mu, 40-50 kg of superphosphate, 20-25 kg of urea, 75-100 kg of plant ash, and fully apply fertilizer and mud Rake evenly. Digging up old stubble with saplings in the mud, following the tillering trend, separate 3 to 5 sturdy tiller saplings into one pier, each pier requires old stems and some stolons. Before the planting of the tall rice seedlings, the tip of the leaf was cut off, and the height of the plant was 30 cm. The planting row spacing is 66-72 cm, the plant spacing is 66 cm, planting 1100-1300 pier per mu, about 6000 basic seedlings.

After the early tube promotes the early emergence of wild rice, the water layer should be kept at about 3 cm until the greening stage. Shallow water irrigation at the tillering stage, water depth of 3 to 4 cm; deep water control tillering in the late tillering period, starting from 7 to 9 cm deep, when the weather is hot from July to August, the water level rises to 10 to 15 cm, and the water is frequently changed; shallow water at the end of the harvest 3 to 5 cm. After returning to the green field, the field was cooked 3 times, with an interval of about 7 days, with emphasis on the application of tillering fertilizer. For the first time, 2500-3000 kg of manure and urea per acre were applied to the field; for the second time, 40-50 kg of ammonium bicarbonate and 10 kg of potassium sulfate were applied per acre, and the fertilizer was applied to the soil. Evenly distributed in the medium and combined with the soil to fully improve the utilization rate.
