The Rao's Rice Man (moving) force live broadcast machine is a patented product researched by Rao Taiping, a farmer from Caohe Town, Jianli County, for more than 30 years. The patent number is ZL962395072, which was awarded a patent certificate by the National Patent Office in August 1997. Rao Taiping insists on using live broadcast machines to produce double-season rice and mid-season rice, and conducts live demonstration of rice human (live) live broadcast live broadcast in Luohe Town and neighboring townships, and continuously improves the live broadcast machine in practice, which should be requested by the majority of farmers. It has trial-produced and sold more than 100 human-powered live broadcast machines, with an accumulated area of ​​10,000 mu.

First, the research background

In recent years, with the warming of grain production and the increase of rural labor transfer, the wages have gradually increased, and the development of agricultural technology has been difficult, and the direct seed production technology of rice has developed rapidly in our county. In 2008, it reached 150,000 mu, but farmers mainly used sowing, and there were some problems in production. Mainly the basic seedlings are difficult to control; the seedling rate is highly correlated with the weather conditions and the quality of the soil preparation during the sowing period. The field seedlings and seedlings are difficult to operate. When the basic seedlings are low, the effective panicle deficiency causes the yield to decrease. When the basic seedlings are too much, the individual growth of the rice is poor, and the stems are stalks. Fine, small ears, poor light transmission in the field, serious pests and diseases; the production of large-scale application of water nursery transplanting, due to the work of transplanting, the density is too thin, as low as 8-9 thousand 蔸 / mu, affecting rice yield Improvement. In the past two years, combined with the implementation of the Hubei Province Grain High-yield Science and Technology Project, we have carried out scientific improvement and high-yield cultivation techniques test and demonstration on the Rao rice live broadcast machine, and the application effect is remarkable.

Second, Rao's rice live broadcast machine structure

The Rao's rice live broadcast machine is simple, light and easy to operate. The human traction can be broadcast 15-20 mu per day, and the small mechanical traction can be 30-40 mu per day. Economical, each unit is priced at 1,000 yuan, suitable for farmers to buy and engage in production.

Third, technical points

1, moderate germination: rice breaks the chest white, it is conducive to mechanical sowing.

2, when timely broadcast, early rice is generally April 10-15, medium rice before April 25 or early May is appropriate, according to the weather forecast to rush to plant.

3. Control the amount of seeding. Conventional early rice is 4-4.5 kg per mu, hybrid rice is 2.5-3 kg per mu, and hybrid mid-sea is 1-1.25 kg per mu.

4, meticulously reorganizing the field: 2-3 days before sowing, the whole field, so that Tian Ping is like a mirror, the grass is pure and fat, the height difference is not too much, and it is naturally dried and sowed.

5, meticulous management: sowing to the current green, wet management, before the 3 leaves to promote roots with drought, shallow moisture, enough to light the field after the seedlings, formula fertilization, after the field, after the application of potassium fertilizer, strong stalks prevent lodging, elaborate Prevention and control of pests and diseases, and the water continues to prevent lodging in the late stage.

Fourth, technical advantages

Seeding with live broadcaster:

1 Simple implementation of rice wide and narrow row or equal row cultivation, rice individuals grow robust;

2 ventilation and light in the field, lighter pests and diseases;

3 when the seeding is carried out, the groove is covered, the cold-proof and the rat-proof, and the lodging resistance is enhanced;

4 The effective panicle ratio is higher than that of transplanted rice, the number of grains per panicle is higher than that of sowing rice, and the number of grains per ear is large, and the yield increasing effect is obvious, generally increasing the yield by more than 5% than that of transplanted rice;

5 machine broadcast can further improve the work efficiency, especially suitable for planting large households, the effect of increasing the income of the festival is significant, and the saving of transplanting workers is 1.4, and the cost of raising the farm is about 150 yuan per mu.
