How to germinate rice seeds to increase seed germination

Rice is one of the largest crops in China and is the staple food of southerners. According to different methods, rice can be divided into indica rice and japonica rice, early rice and mid-late rice, japonica rice and non-japonica rice. The hybrid rice invented by Yuan Longping in the previous years actually increased the yield of rice. Generally, the yield of rice has a great correlation with the quality of seeds. Among them, the seed's clarity, seed weight, seed moisture content, seed germination rate And so on, are the key factors in rice quality. Seed winnower, also known as seed blower, is involved in the analysis of seed's clarity and can improve the clarity of the seed; the counting instrument is an indispensable instrument for the determination of seeds' grain weight; and the precision seed germination box can provide the most appropriate temperature for seed germination. Let the seeds grow in an optimal state. In addition, to increase the germination rate of the seeds can also be achieved through the germination step. Here we analyze how to properly germinate rice seeds.

Germination requirements to achieve "fast, homogeneous, uniform, strong." "Fast" means that within 3 days it is able to promote good buds, "Qi" requires that the germination rate reach 85% or more, "uniform" means that the root buds are long and uniform, and "strong" means that the young buds are strong, the proportion of root buds is appropriate, and the colors are Fresh white, odorless, no wine, no mold. The standard of germination: the length of roots and shoots differs depending on the temperature. The temperature of early rice sowing is low, the length of roots is one grain, and the length of buds is appropriate. Roots and shoots are prone to breakage when they are too long, reducing the rate of emergence and uniformity. When the middle rice is sown, the temperature has been raised, and the length of the root buds can be shorter. When the late rice is sown, the temperature is already high, and it can be planted by exposing the thorax to whiteness. In order to shorten the adverse effects of high temperature, the double-season late rice should be primed to dew. Seed germination process: high temperature breaks the chest, from the initial germination to the broken chest, the respiration is not strong, the seed itself can not produce heat quickly. In order to neatly break the chest, the temperature should be properly increased, generally controlled at 35 ~ 40 °C, should not exceed 40 °C. It is best to insert a thermometer and turn it over at a temperature of 40°C. The germination stage generally does not advocate watering. When the seeds are in the germination process, the respiration will gradually increase. The water will block the pores of the seed heap, affect the gas exchange, cause anaerobic respiration, produce alcohol, and even become sticky. The regiment cannot be dispersed by itself and has a great influence on germination. With proper temperature and long buds, after the seed ruptures, the respiratory function is strong. It needs to consume a lot of oxygen and release a lot of heat. The temperature of the stack will increase by itself. At this time, the temperature should be controlled at 25 to 30°C. If it continues at 35°C or more, then Easy to make roots, buds grow too fast, thin but not strong, while the temperature can easily rise above 40 °C, causing high temperature burning buds. At this stage, we must pay attention to regulating the relationship between moisture, temperature, and oxygen so as to avoid the occurrence of root-budget phenomena. When the roots and shoots have reached the required length for germination, the rice can be roasted in the room to accommodate the natural temperature of the field after sowing. Buds should be sowed immediately after sowing, in case of bad weather, can be further dilution of the bud, until the weather turned better after sowing.

Manual Saw Blade Sharpening Machine

  1. The clamp mould and knife wheel are designed finished to guarantee the central line of workpiece and knife wheel is exact. Thus, the outer angle, inner angle and pipe end machining may be finished evenly at one time.So this gear sharpening machine has the high performance.
  2. This sharpening machine makes use of the change of belt wheel to shift different rotate speeds, so the life of blade may be as long as possible according to different metal materials.
  3. The double-step feeding system saves working time. And the speed of Saw Blade Sharpening Machine is slow for regulating easily.
