Rice direct seeding planting technology and management

Direct seeding of rice is an efficient planting method suitable for multiple regions and seed varieties. However, late-maturing varieties may not be suitable for direct seeding due to their longer growth cycle. Let’s learn about the direct seeding technology and management of rice.

1. Planting preparation

Apply sufficient base fertilizer in the field and control the sowing amount per mu to 25 to 30 kilograms. Whether sowing in rows or broadcasting, ensure that the seeds are evenly distributed. After sowing, shallow harrow, make trenches, and irrigate to keep the soil moist for 2 to 3 days. When the moisture has dried up naturally and there is no water on the bed surface, use herbicides to seal the soil in time to reduce the growth of weeds.

2. Seedling management

When the seedlings grow to the two-leaf and one-heart stage, weeds such as barnyard grass and crabgrass may appear in the field. Choose a sunny day after 4 p.m. or windless weather to weed and ensure that the herbicide is applied evenly. Rewater within 2 days after application and maintain moisture for 3 to 5 days to promote weed death. Subsequently, apply greening fertilizer to promote the growth of seedlings.

3. Seedling supplementation measures

If the seedling conditions after direct seeding are not ideal, or the seedlings die due to weeding, they can be transplanted from other densely populated seedling areas to fill the gaps and ensure that the seedlings in the field are even and grow uniformly.

4. Herbicide treatment

For weeds that cannot be removed in one go, timely remediation should be carried out to ensure the weed control effect and create favorable conditions for rice growth.

5. Dealing with dead seedlings and fertilizer and pesticide damage

Weeding and fertilizing during the hot season may cause rice seedlings to become stunted, red, yellow or have black roots. At this time, measures should be taken immediately, such as spraying "Bihu" and trace element foliar fertilizer to regulate crop growth, or spreading special rice fertilizer and zinc-silicon fertilizer to help rice resume growth.

6. Normal management

During the normal growth period of rice, inspect the fields regularly to observe whether there are any diseases or pests. The focus is on preventing and controlling diseases such as rice blast, sheath blight, rice false smut, as well as pests such as stem borers, leaf rollers, striped stem borers, yellow stem borers, and rice planthoppers. Especially during the breakthrough and filling stages, prevention and control should be strengthened to reduce the impact of diseases and insect pests on yield. At the same time, be careful not to cut off water too early to avoid causing bacterial wilt and affecting yield.

7. Rational use of drugs

There are many options for rice pesticides, and the specific drug to use should be decided based on local actual conditions and the recommendations of agricultural supply stores. Farmers should actively participate in learning agricultural knowledge and apply it rationally to achieve increased production and income.

The above are the key points of direct seeding rice planting technology and management. Through these meticulous management measures, I hope everyone can ensure the success and high yield of direct seeding rice planting.
