Abstract : Rice cultivation and cultivation is based on the continuous development of experience and lessons learned from rice dumplings. This technology not only inherits the advantages of rice throwing technology, but also overcomes the shortcomings of casting technology. It is a new technology that should be promoted to increase rice yield.
In this year's township, 200 hectares of cultivated seedlings were planted and transplanted in our village. The results have shown good results and laid the foundation for the promotion of a large area next year. The nursery, field management, and prevention and control of diseases and weeds in rice cultivation are roughly the same as normal rice cultivation and management. This article will not go into details. The following sections mainly introduce several key technical aspects of cultivation.
First, choose a good species
Large and medium-late-maturing varieties with large panicle type, strong tillering ability, disease resistance, salt and alkali resistance, and cold resistance were selected. Such as Jixi 809, Jida 6, Jida 718 and so on.
Second, swing plate sowing
1, swing plate: first set the bed through the bottom water, until the water sinks, will be loaded with nutritious soil (or nursery substrate) plate placed on the bed, and then use the board to suppress, so that the plate with the bed full contact, There should be no gap between the plate and the bed, and the soil around the plate should be covered with water.
2. Seeding: When the average temperature on the day stably passes 5°C, I will start sowing on April 10th, when the temperature in the shed is stable at about 12°C, and sowing in more than 95% of shoots buds in each eye 3-4 Grain, sowing 80% first, and then use 20% to find cavities or points below the amount of additional broadcast.
3, broadcast volume:
434 hole plate: Transplanting specifications 9x4 inch, need 700 plates, with 80-9 90 kg of buds.
434 hole plate: transplanter specifications 9x5 inch, need 600 plates, with buds 70-80 kg.
434 hole plate: transplanter specifications 9x6 inch, need 500 plates, with buds 60-70 kg.
648 hole plate: transplanter specifications 9x4 inch, need 500 plates, with buds 90-100 kg.
648 well plate: Transplanting specifications 9x5 inch, need 420 plates, with 80-990 pounds of bud species.
648 hole plate: transplanter specifications 9x6 inch, need to use 350, with buds 70-80 kg.
Third, the ground pendulum
1. Site preparation: Before the site preparation, it is necessary to clean up and maintain the irrigation drainage channels to ensure smooth flow. In autumn till the depth of the field is 15-20, the level of drought will be fine, and in early May the field will be filled with water, the dry soil will be combined with the water preparation, and the rotary field will only be used for water preparation, the drought and soil shall be dry and flooded, the soil level shall be dry, and the soil shall be leveled. Ditch, combine with the field to make a good pool. Water preparation shall be carried out 5 to 7 days before transplanting. Sandy soil blocks shall be planted on the afternoon of the day of transplanting or on the morning of the day. The leveling shall be done so that the water in the pool is not exposed to mud, and the fertilizer will not be discharged.
2, planting
(1) Period: To achieve a three-view, look at the sky, see the water, and see the seedlings. When the average temperature on that day is stable at 12°C, I usually start transplanting on May 10 and it is advisable to plant a rice plant in June.
(2) Specifications: According to the fertility and seedling conditions, generally 9x4 inch, 9x5 inch, 9x6 inch, high-fertility plots should be thin 20-25 points /?, low-fertility plots should be dense 25-30 points /?; Large seedlings, high rate of picking, thinning, small seedlings should be dense; difficult to lift water during the tillering season, land susceptible to drought, plots where the water layer is too deep and difficult to drain during the tillering season, suitable density, guarantee effective ear 450- 500/?.
When planting, it must be ensured that the row spacing is uniform, the depth of the planting is controlled at 1.5-2, and the top surface of the nutrition soil of the seedlings is flush with the mud surface. After the land is well-prepared, the Wangshui Wang mud is placed in a moderately soft and hard state to prevent the soil from becoming hard and affect the quality of transplanting.
Fourth, the advantages of cultivation technology
Seedling rearing seedlings inherited the advantages of throwing seedlings, and achieved a sparse planting, with armpits, good root growth, robust plants, mechanical transplanting does not hurt the roots, plug seedlings quickly. The transplanting and transplanting machine is used for transplanting rice seedlings, so that the throwing seedlings can only be thrown manually, the row spacing of the seedlings is uneven, and the manual throwing defects are greatly affected by the weather.
