Greenhouse Seed Trays

Seedling preparation: according to the seedling field and planting field area ratio of 1:100, Artificial furrows, The net border width is 1.4 meters, 30 cm wide ,15 cm deep, Water leveling, Ensure that the field height difference does not exceed 3 cm. If it's dry before sowing, The furrow was cracked, Can be filled 3 days in advance, Make the bed moist. When the furrow crack is large, It can be filled with fine soil. Each mu of seedling pond is equipped with 9 cubic meters of fine soil. The water content of the fine soil is massed by hand, It's good to fall, Too dry and too wet is not conducive to sowing, Required by the end of April, Cover with film, Rain and wet. Machine inserted rice seedling substrate was used as soil fertilizer. A total of 4.5 kg of dry straw (140 g of net dry seed per plate) was prepared in every mu of field with no branch stem, full seeds and germination rate of more than 90%). Use 2.2-2.4 ml to soak 2 and 15 g 10% imidacloprid in water 8-10 kg, Stir well and soak 5-6 kg rice seeds for 50-60 hours. When the seed has enough water, Special seed dressing for every 5 kg of rice, Dry and sow when the bud is broken and the chest is white. According to the stubble, planting period to do a good job of seed germination, Connect the seeding period. Wheat stubble falls on May 23-25, Transplanted June 15-17, The seedling age was controlled at 20-22 days. Wheat stubble falls on May 25-30, Transplanted June 15-25, The seedling age was controlled at 18-22 days.

Second, operation steps: choose plastic plate or double film seedling raising method. (1) Fill the lining with appropriate amount of bed soil, To secure the border with wood or straw, Then spread the hole film or floppy disk, Fill in nutrient soil, The thickness of soil layer is 1.8-2 cm. Before sowing, the seedling bed was filled with foot water. (2) According to the amount of sowing per plate (140 g net dry seed weight), The maximum sowing amount should not exceed 160 g) to calculate the seed quantity of seedling plate. Seeding requires even seed, To ensure that the amount of rice seed per square centimeter 2-3 grains, No replay, missed broadcast. Cover the soil in time, The thickness of overlying soil is about 0.5 cm, It is appropriate not to expose seeds. Sprinkle a small amount of straw (or grass) on the plate as a barrier, To prevent the "plaster" phenomenon, Then cover a film, Compaction around, Cover the film with a straw curtain or sprinkle straw evenly. (4) Fill with water after sowing, Ensure the need for moisture.
