Rice seeding machine assembly

Live broadcast technical specifications and key points and product introduction: Rice direct seeding technology is simple and practical, has the advantages of labor saving, time saving, cost saving and efficiency increase, which is convenient for farmers to accept and master. Using machine live broadcast technology, 5-8 mu can be planted per hour. Sowing in a day can reach about 40-50 mu, which is nearly a hundred times more effective than manual transplanting. Because the traditional breeding and transplanting links are omitted, it can save 2-3 labor per mu; according to the ratio of 1:8 per mu of seedling field to Honda According to calculation, it can save 0.125 mu of seedling field, increase the yield by about 30KG per mu, save cost and increase efficiency by 40-50 yuan, and the benefit is obvious. However, the live broadcast technology also has its weaknesses. There are special requirements in some aspects of rice cultivation management, such as all seedlings, chemical weeding, and lodging prevention, etc., to ensure the successful implementation of the live broadcast technology. 1. Technical requirements and field management of rice direct seeding machine before use 1. Fine land preparation The ground preparation quality of direct seeding rice is higher than that of traditional rice seedling transplanting. Field preparation should be fine, so as to be "early, peaceful and suitable". Early means early tillage, early rake, and early stubble removal. That is, after the previous crops are harvested, use a rotary tiller to turn the remaining weeds, rape, wheat and other stalks and root stubble into the mud; in the second round of rotary tillage, use the base fertilizer that has been applied to the field Turn it into the mud, rake and level it, release water to settle for 24H-36H according to the degree of soil mush, and then sow. Leveling means that the field should be leveled. The flatness error of the field should not exceed one inch, and the soil will not be visible to an inch of water. Otherwise, the low-lying area will cause the rotted teeth due to the accumulation of water, and the high-placed teeth will be easily dried by the sun. , Affect all seedlings. Suitable means that the soil surface in the field is moderately soft and hard during drainage and sowing. During the field preparation, the soil texture should be properly rotated and not too muddy to prevent seedlings from being deep in the mud. 2. Choose good varieties Because the direct seeding rice root system is shallow, mostly distributed in the soil layer, easy to lodging, it is necessary to choose high-yield, hard stalk, medium plant height, and high-quality varieties with compact plant types. The direct seeding machinery is a semi-precision seeding machine, and the seeding amount can be adjusted between 3 kg and 8 kg per mu. The sowing rate per mu is less than 3 kg, which cannot meet the requirement of uniform seeding. Therefore, it is most suitable to choose japonica rice varieties with a sowing rate of more than 3 kg per mu. Hybrid rice is not suitable for direct broadcast. Machine direct seeding technology is mainly used for early rice and single-season rice, and early indica and medium japonica varieties are suitable. 3. Sowing carefully Seeds are used to promote teeth. Before soaking, the seeds should be air-dried, screened, and dried to prevent more impurities from affecting the sowing quality. The seeds must be tested first to germinate, and the germination rate is required to be above 95%. Then soak the seeds to urge the teeth, and urge the teeth until the heart is broken and white, and the root teeth cannot be lengthened to prevent the seedlings from being scratched by the machine sowing. Proper sowing, adjust the sowing amount reasonably according to different sowing dates, different varieties and different fields. http://www.toenter.com.cn/
