Rice cultivation The quantitative cultivation is a rice cultivation experiment combined with the soil texture and production level of the rice area of Qilin District of Qujing City, and the integration and application of the technology for accelerating the high yield of rice. Its core technology is: strong, expanding, reducing seedlings, adjusting fertilizer, and controlling water.

First, cultivate strong

1. Soaking seeds: Before soaking seeds, choose sunny weather for 1-2 days, soak seeds and herbs, fresh amine, soak seeds for more than 48 hours, seed heat preservation and germination, and white sowing.

2, seeding amount: deducted seeding and sowing, the amount of seeding per field is 4 kg (5 kg of germination seeds).

3, seedbed fertilization: base fertilizer on the basis of conventional fertilization, each application of 2-4 tons of compound fertilizer.

4. Fertilization technology: When the two leaves are one heart, the milk fertilizer is applied, and 2 kg of hydrogen ammonia is applied to each field. Three leaves and one heart are used to promote the manure, and 2 kg of urea per paddy field; 1 month before transplanting, the manure is applied, and each minute is applied to the field. 2 kg of urea.

5, breeding tube water technology: Wet Yuchao ditch to maintain semi-ditch water, shallow water fertilization, two leaves and one heart after the dry and wet alternate.

6, the delivery of drugs: control rice seedlings and rice planthoppers, combined with the application of martilage, with 20% tricyclazole + imidacloprid or 5% Regent spray.

Second, transplanting age

Wet nursery, 6-leaf transplanting, seedlings with 2 cockroaches (2 below 2 leaves).

Third, transplanting specifications and requirements

1. Transplanting specifications: planting and spacing, 8 inches × 3 inches, 25,000 bushes per acre, planting 2 to 3 seedlings per cluster to ensure 5 to 60,000 seedlings per acre.

2, transplanting requirements: the use of pull wire manual point planting. Ensure the density and specifications of the planting, so that shallow water can be inserted shallowly, the planting depth is 2 cm, and the water layer in the field is no more than 3 cm to ensure that the tillers are fast-growing.

Fourth, fertilization

1. Base fertilizer: 1000 kg of farmyard manure before application, (5.01 kg of nitrogen fertilizer, all phosphate fertilizer and 50% of potash fertilizer) was applied 1 day before transplanting.

2, split fertilizer: (5.01 kg of nitrogen fertilizer), 10-15 days after transplanting with herbicides, keep the water layer for 3-5 days.

3. Promote flower fertilizer: (3.34 kg nitrogen fertilizer + 50% potassium fertilizer) is applied when half of the inverted 4 leaves are taken out.

4, Baohua fertilizer: (3.34 kg of nitrogen fertilizer) applied when the inverted 2 leaves were extracted.

V. Daejeon water management technology

Daejeon tube water: shallow - wet - drying - shallow - wet - drying

1. From the transplanting to 20 days ago, the shallow water (2-3 cm water layer) management in the early stage.

2, 20 days later until the leaves enter the first leaf before the inverted four leaves, shallow water and wet alternate management.

3. When the leaves enter the first leaf of the inverted four leaves, when the total number of stems of the group reaches about 80% of the target number of seedlings, the water is removed from the sun, so that the peak seedlings are controlled at 1.1-1.3 times the number of panicles. To the extent that it does not trap and crack. At this time, the rice leaves are green, the leaves are strong, the base becomes round and hard, and when the leaf age enters the inverted four leaves, combined with the application of flower fertilizer, the shallow water and the moist are alternately managed to ensure the timely closure of the rice heading period.

4. Drain the water and dry the fields 10 days before the harvest.

Sixth, pest control

The rice in Qilin District is mainly the prevention and treatment of "two diseases and one insect" (rice blast, rice smut, rice planthopper), and prevention and control should seize the critical period.

1. 35-40 days after transplanting rice, use tricyclazole wettable powder + imidacloprid to control leaf blast and rice planthopper once.

2, before rice heading, when the blast is 5% broken, you can choose 21% imidacloprid wettable powder 8-16 g / mu, 20% jinggangmycin powder 75-100 g / mu, 40% thiocyclazole suspension 200 ml / mu, evenly sprayed with 60 kg of water.

3. At the heading stage, thiocyclazole emulsifiable concentrate + Jinggangmycin + imidacloprid was used to control epiphyseal disease, rice smut and rice planthopper.
