Accumulation of rice seedlings in plastic trays
2022-08-22 18:03:32
Technical Overview: In the plastic trays, use dry and dry methods to cultivate strong seedlings suitable for throwing (pendulum) planting, and a paddy field technique for scientific cultivation and management after field throwing. This technology has the outstanding advantages of high production and stable production, labor saving and labor saving. Especially in Jiangsu Huaibei and Huaibei rice production areas, it can not only effectively solve the limiting factors of direct seeding and late seeding transplanting due to late planting and breeding, shortening the growth period, planting season and other constraints, but also can reduce labor intensity. Improve rice yield and benefits.
Increased production and efficiency: Acres increased by more than 5%, and the increase in net yield was more than RMB 80.
Technical points:
1. Core Technology 1 Cultivate a suitable throw. The flat land with fertile soil is selected as the seedbed, and nutrient soils are made with seedbed special fertilizers such as strong nutrients. According to the standard of 1:35-40 in Datian, a plastic floppy disk (434 holes) of 55-60 sheets per mu. According to the appropriate paddy date for the safe rice heading date in the local area, the conventional glutinous rice field should be about 3 kg per mu and the hybrid medium japonica rice should be about 1 kg. After soaking, it should be evenly sowed with a special coating agent, covered with nutritious soil and poured. ) Plantar trampoline soil, removal, covered with grass, timely removal of film fertilizer and watering. The average age is 20 to 30 days, and leaves (pendulum) are planted when the leaf age is about 4 to 5 leaves.
2 accurate throwing (pendulum) planting technology. Fine field farming, so that the difference between the height of the field does not exceed 3 cm, see the sky, see the seedlings throwing (pendulum) planted, to promote the orienteering, throwing enough seedlings to increase uniformity. Routine japonica rice throwing (pendulum) 1.8 to 20,000 holes, 2 to 3 seedlings per hole, hybrid medium japonica rice throwing (swing) 1.5 to 17,000 holes, 1 to 2 seedlings per hole, throwing (pendulum) to maintain shallow water layer after planting , promote live tree delivery.
3 accurate management of fertilizer. According to the characteristics of throwing (pendulum) pods after rice planting, such as short easing period, early living trees, fast leaves, early tiller, etc., adopting front- nitrogen rearward shifting balanced fertilization techniques, the ratio of general basal rice to panicle fertilizer is 6:4. ~5:5 is appropriate. Datian Moisture Management adopts a method of moist live trees, shallow moisture hoeing, early sun-controlling of stalks, and booting to heading intermittent irrigation.
2. Supporting Technology 1 Select the appropriate variety. The rice varieties with strong disease resistance and strong lodging resistance, medium and large panicle types were selected.
2 comprehensive prevention and control of pests and weeds. According to the law of occurrence of rice pests and diseases, comprehensive prevention and control are carried out to effectively control pests and diseases.
Appropriate area: all rice areas in the province.
2012 promotion basis: In 2012, the province's promotion and application area was 3.07 million mu.
Expected target for 2013: The province will promote 3.5 million mu, increase production by 5% or more, and increase the net profit by more than 80 yuan.
Focus on promoting counties (cities, districts): Hai'an, Rugao, Taixing, Gaoyou, Baoying, Sheyang, Suining, Binhai, Xiangshui, Huaiyin, Xishui, Guannan, Donghai, Fuyang, Sihong, and Chengcheng. Henan, Tongshan, Zhangzhou, Xinyi, Suining, Peixian counties (cities, districts).
