Rice throwing rice dumplings is a technically-reduced cultivation technique with a high degree of technical maturity in the current rice reduction culture technique. The technology has been used in production for many years, but many farmers have not mastered the technology because of the breeding. In place, plastic trays tend to produce string rooting, which not only leads to an increase in the number of throwing rods, but also causes uneven casting, increases the amount of seedlings used in the field or leads to reduced yields.
Plastic trays for the prevention of stringent rooting should do the following:
1. Select the irrigation and drainage of rice fields;
2. To open a trench system in the Putian Valley, to make sure that the irrigation and drainage are smooth, to meet the requirements that the rainy days will not reach the water, and that the weather will not be flooded when the weather is dry;
3, try to choose the 434-hole large oyster plate seedlings; hoe tray filling soil should not be too full, after sowing should scrape the rake disk surface mud;
4, do a good job after the sowing of water management: After sowing to maintain moist seedlings, no drought after emergence, no watering, waterproof and waterproof surface.
5, no irrigation and fertilization. If the seedlings are de-fertilized or applied, they can be sprayed or applied with 1-2% urea solution.
