How to grow rice 




Machine transplanting seedlings of rice

Machine-transplanting seedlings has the advantages of high efficiency, suitable for large-scale production and conducive to production standardization. However, due to the large one-time investment in the purchase of rice transplanters and the small scale of planting areas, it is impossible to fully promote the development of rice transplanters in my country at present. Therefore, in areas where conditions permit, the development of machine transplantation should be vigorously promoted. This is the direction of my country's future development of rice production.


· How to increase rice production?

Rice is the staple food of our daily life, and rice is also an important crop in our country. So, do you know how to grow rice to increase the yield of rice?


If you want to increase rice production, you can refer to the following methods for management:


1. Increase the number of ears. ① Cultivate strong seedlings. It provides a good foundation for early re-greening and early tillering after planting. ② Reasonable dense planting. According to the number of ears planned to be harvested and the estimation of the tillering situation of the seedlings after planting, the basic seedling number should be inserted (thrown). ③Promote the early occurrence of low tillers and control the low occurrence of high tillers. Promote the early onset of low tillers, expose and dry the field in time after inserting enough seedlings, control the ineffective tillers at high nodes, concentrate nutrients on the effective tillers with early onset, and increase the rate of tillers into ears.


2. Increase the number of grains per spike. ① The stalk is thick before promoting the differentiation of young ears. On the basis of strong seedlings, in the tillering stage of the field, it is necessary to ensure the supply of nutrients necessary for the stable growth of rice plants, so that the rice stalks are strong, and the rice panicles have strong stalks, so that there is a good foundation for large panicles. ②Sufficient nutrients are provided for the differentiation of young ears. Usually at the beginning of the differentiation of young ears, if the leaf color is lighter, it is necessary to apply "flower promoting fertilizer" to promote differentiation to form more spikelets. In the middle stage of young ear differentiation and development (about 20 days before heading), if the leaf color is light, "flower-preserving fertilizer" should be applied to reduce the degradation of spikelets and increase the growth rate of spikelets. ③Adjust the temperature with water to increase the rate of solidification. In case of dry and cold weather (such as cold dew wind) during the heading and flowering period, diving can be used to moisturize and increase the temperature, reduce the damage of low temperature and dryness to the rice, and increase the seed setting rate. ④Increase dry matter accumulation before heading. Pay attention to the nutrient supply required for growth before heading, but do not grow too vigorously, so that photosynthetic products will accumulate to ensure that more substances are transferred to the grain after heading, and the seed setting rate is improved.


3. Increase grain weight. ①Ensure that the young ears have good nutritional conditions at the later stage of development, so that the husk grows larger and can hold more grouting material. ② During the maturity stage, moist irrigation is adopted to grow roots and preserve leaves, forming more photosynthetic products and making the grains fuller. ③In the growing period of rice, combined with the spraying of " 481" plant growth regulator, it is beneficial to promote the formation and growth of leaves, increase photosynthetic capacity, promote filling speed, increase grain weight, and increase grain protein and nitrogen-based acids. Content, improve the quality, shorten the growth period, promote the increase of grain maturity, and gain valuable time for planting double-season rice.


· How to deal with rice lodging farmers should remedy?

During this period, rice is just in the middle and late stages of filling, and it is particularly prone to lodging under the influence of wind. When the paddy field has lodging, it is necessary to remedy it in time. How should the farmers respond to the lodging of rice?


The following methods should be adopted to deal with rice lodging farmers:


1. Timely ditching and drainage to clear the land. This pair slows down the spread of sheath blight, prolongs the functional period of leaves, promotes the continuous grain filling, and prevents ear germination and stem rot.


2. It is not suitable to tie the rice paddy to the lightly lodging rice. Because the lodging rice plants generally fall back homeopathically, the rice ears, panicle nodes, and the first and second leaves are basically exposed on the surface. 3 to 5 days after the lodging, due to the automatic regulation of the rice plants, they will Make the leaves and cobs automatically tilt up, especially in the fields where the lodging is not serious, the rice plants have a stronger ability to automatically adjust. But after the lodging, supporting the rice to tie the handle, it will artificially destroy the natural distribution of the rice ears, panicles, and leaves, which will aggravate the mechanical damage and cause more serious lodging losses.


3. For the heavily lodging rice, as long as the rice that has not completely fallen to the ground, it can be rescued by artificially tying it into small handfuls. It can be tied with nylon rope or weed. In this way, you can avoid a dead end. 


At present, there are four main methods of rice cultivation in my country: "hand transplanting", "machine transplanting", "mechanical direct seeding" and "throwing seedlings", each of which has its own characteristics. However, due to different cultivation methods, their production input costs and output levels are also different. Which cultivation method should be used in rice cultivation should be scientifically determined according to factors such as the size of its production scale, the amount of production funds, and the characteristics of the technology itself. The specifics are:


One is to have a certain scale, at least hundreds of acres of land.
