The Direct seeding of Rice in Jingtoushan Farm

Our farm has nearly 700 hectares of paddy fields. Direct seeding of rice was implemented in 1987 and fully popularized in 1999, with a success rate of 100%. The main point of its live broadcast technology is to master the following three hurdles. First, the whole field is closed. Paddy field ploughing, ploughing, irrigating, machine finishing, cattle finishing can be done. Then wipe the bar and smooth the field. Use a self-made trench board to trench. The trench board is 2 meters long, 45 centimeters wide and 3 centimeters thick. Two 30-centimeter long handles are nailed to the left and right sides of the board, and the width between the handles is 1.6 meters.

The selection of parents selected the international famous rice variety Basmati, the Youxiang soft strain mutated by solar radiation and Xiangshimiao No. 2 as the male parent. Qingzhen 8, which has high yield, high resistance and wide adaptability, is used as the female parent. 2. after the progeny selected a single plant in the late production in 1991, various types of single spikes with medium dwarf and plant grain shape similar to those of fragrant silk seedlings were selected from the materials separated from F2 and F3 generations, and then multiple generations were selected and propagated and compared with single plant lines.

Successful breeding of a New Rice Variety resistant to Cancer

Since the beginning of this century, rice stripe blight has continued to break out in a large area, and even led to no harvest of rice farmers. Rice stripe blight has been regarded as rice "cancer". In the past, it has been recognized by the market as the main rice variety "Wuyujing 3" with the best taste and quality in Jiangsu Province and its surrounding areas. Because of its high infection with stripe blight, the planting area has decreased sharply in recent years. Some varieties resistant to stripe blight either have defects in high yield and stable yield, or have not been fully recognized by the market in rice quality. Rice farmer

Fertilizer application of mechanically inserted rice

The total amount of fertilization of mechanically planted rice is about the same as that of artificial hand-planted rice. But how to apply it in different periods, machine-planted rice is different from hand-planted rice. The main reason is that the tiller node position of mechanically inserted rice is low and the tillering stage is long. in order to control the panicle number of the population within a suitable range, the key point of fertilizer operation should be to improve the application period of tillering fertilizer in order to adjust and utilize the most suitable tiller node position and control the mid-stage population. and increase the application of panicle fertilizer, promote spikelet differentiation and strive for large panicles. The characteristics of machine-planted rice and hand-planted rice determine the base and tiller fertilizer of machine-planted rice.

Key points of field stage management of mechanically implanted rice

Due to the limitations of seedling age, seedling age, sowing date and plant characters, mechanically implanted rice requires higher tillage quality in transplanting field. At the same time, machine planting realized wide row, fixed hole, fixed seedling and fixed depth planting, which met the population basis of high-yield rice population quality cultivation. Therefore, only if we do not do a good job in the field stage management of mechanically inserted rice, can we ensure the early and stable growth after planting, strive for full panicle, attack large panicle and win high yield. 1. Field preparation: 1. Fine soil preparation: Rotary tillage should be used to kill stubble in field tillage. the depth of rotary ploughing is about 12-15 cm, and the water should be fully absorbed after water.

Advantages and matching cultivation techniques of Machine-sown Rice

The common ways of rice transplanting are land washing, machine transplanting, throwing transplanting and so on. According to the law of rice growth and development and the characteristics of soil and climate in Hunan, we have developed "Summer 2BR-100, 2BD150 rice seeder" (which has applied for a patent). By using machine sowing rice, we have comprehensively assembled high-yield practical techniques such as ridging cultivation, mud valley cover, open trench, single-grain shallow sowing and so on, thus solving the problems of whole seedling, uniform seedling, strong seedling and non-rotten seedling. It gives full play to the tillering potential of rice.
