Advanced rice field management

High-quality rice has nitrogen retention at the later stage of its growth, and cultivation management should avoid excessive nitrogen in the later period and affect grain filling to protect the roots, prevent premature aging, and increase the rate of seed setting.

1. Appropriate root dressing.

Early rice can be top-dressed once every 7 days in the full-heading stage, with 150g of monopotassium dihydrogen phosphate and 500g of urea mixed with 75kg of water per acre. Late autumn rice is cool, temperature difference between day and night is large, and light is sufficient. Top dressing effect is better.

2, scientific water.

Sprinkle back to shallow water during heading and flowering period, keep moist until harvesting, and feed horse water 5 to 7 days before harvest. Never avoid premature watering to prevent late high-temperature ripening of early rice, early harvesting of seedlings and late grain filling, affecting yield. . In addition, when the late rice headings meet the north wind or cold dew wind, they must stay in shallow water for several days to prevent cold.

3, pest control.

During the break period and heading stage, spraying should be used to prevent and control panicle blast, sheath blight, and stem borer, etc.; after heading, attention should be paid to the prevention and control of rice planthoppers, so as to avoid wearing through and affecting yield.

4, the key to cultivation and management.

The key technologies for the late growth management of high-quality rice are mainly reflected in the ability to improve the production and operation of the product. During the late stage of cultivation of high-quality rice, which is sensitive to the application of nitrogen fertilizer, root-to-top dressing measures should be adopted to raise the root and protect the leaves. After flushing, consider applying nutrients, rare earth, or potassium dihydrogen phosphate in divided roots.
