The technique of raising and strengthening Rice seedlings by Machine transplanting
With the improvement of the intensive level of rice production, mechanical transplanting has become an inevitable trend. One of the keys to the production of mechanically implanted rice is to raise strong seedlings. The following measures can be taken to raise and strengthen seedlings:
1. Apply seedling strengthening agent. Seedling strengthening agents are usually mixed with subsoil. First, mix a small amount of fine soil and seedling strengthening agent evenly, sprinkle it on the bottom of the seedling plate, and then add the subsoil. In order to avoid mixing and spreading unevenly because of too much subsoil, resulting in uneven distribution of seedling strengthening agents, resulting in dwarfing of seedlings in places with too many seedling strengthening agents, resulting in seedling shedding and affecting the quality of mechanical transplanting.
two。 Cover the film. Because of the short seedling age, it can be covered with plastic film to increase temperature and keep moisture in the process of raising seedlings. That is, along the direction of the seedling board, a row of thick bamboo poles are placed on the side where the two seedling trays overlap, and then covered with film. The film forms the shape of the roof, which is not easy to be close to the soil surface, affecting ventilation. When it rains, Rain Water will flow along the film to the drain.
3. Cover the straw curtain. Raising seedlings requires that the mulch maintain a light transmittance of 10% to 15%. In the process of raising seedlings, the film can be covered with straw, sunshade net, grass mulch, straw curtain and other mulch, and the straw curtain is the best. The straw curtain is made of two groups of plastic ropes of suitable thickness, each with a piece of straw, one upside down, knitted back and forth, and can be used for many years. Two grass curtains with a length of 3.5m and a width of 0.6m are prepared for every 667 square meters of field. The light transmission is uniform, which can make the seedlings uniform, uniform and strong, which meets the requirements of machine planting.

Key points of cultivation in transplanting stage of mechanically implanted rice
First, make a good start and manage the seedling field well. 1. Look at the seedlings and fertilize them well. It is generally carried out 3-4 days before transplanting; the amount of fertilizer and application method should depend on the seedling color; the detached seedlings with faded leaves should be evenly sprayed or poured with urea 4-4.5 kg per mu to water 200 kg in the evening, and should be sprinkled once after application to prevent fertilizer-burning seedlings; the seedlings should be sprayed with urea 1-1.5 kg per mu and 60-70 kg water per mu The leaves are thick green and the leaves are covered with seedlings, do not apply fertilizer, water control measures should be taken to improve the quality of seedlings.
