First, fine bed science seedlings:
The first is to choose a good bed bed soil. Irrigation and drainage is convenient, the field is flat, and near Daejeon, rice fields with convenient transportation are used to make paddy fields, and Ida-tae is 1:60-70 (area). The seesaw must be flat, light, and real. The bed and soil require fine, loose, fat, and turfgrass. Bed soil is preferably irrigated soil in dry land, surface soil in paddy soil, river mud, and sulcus mud. It is applied after being dried and sifted through sieves (screens 4-5 mm). The beds are suitable for dry weather preparation, with 200 kg per mu of field. Fertilizer is generally not mixed fertilizer, if the soil is mixed fertilizer. Every 50 kilograms of fine mud, add 100 grams of potassium bicarbonate, 200 grams of superphosphate, evenly mix, heap bored use. Before sowing, bed soil should be ensured, so that it is enough to attract people. Covering the soil is different from planting the bed soil, and the thickness should be moderate (mesh size 5-8mm). Dry soil loose soil.
The second is to timely sowing, quantitative transplanting machine transplanter transplanting seedlings on the strict requirements of age, generally 18-20 days is appropriate, therefore, according to the cultivars cultivars, machine insert progress and item count transplanting period, sowing in batches, growth period Long varieties, dry sowing, dry cultivation, short growing period, timely planting timely planting. The amount of broadcast should be appropriate and the valley should be even. Generally, net sowing is 450-500 kilograms, ie 0.7-0.75 kilograms per square meter. According to the quantitative scale, Shimoda is planted. Immediately after sowing, cover seed soil (in order to prevent topsoil knots, water can not be sprayed on cover soil, should be allowed to spray naturally), to prevent seed buds from delaying, to promote rooting, to ensure seedlings and shoots, then to cover the film and straw .
The third is to manage seedbeds, seedlings, and seedlings. Putian covered with film and straw curtain, timely reveal after Qimiao; after sowing, generally do not water before uncovering the film, keep the beds moist in the early stage, 2 leaves and 1 heart after each irrigation mouth thin layer of water, the term dry off. Before going to bed, look at the dehydration for 1-2 days, so that the hard sheeting can facilitate machine insertion. At the time of one leaf, Sheung Shui top-dressed. Machine-planted seedlings are susceptible to withered damage. At the tip of the 2-leaflet, it is 1500-2000 times that the liquid is loose. 2-3 days before planting.
Second, high standard transplants:
One is to precipitate the mud, thin water machine plug. In order to improve the quality of machine plugs, to avoid planting too deep or impetuous, fall down, Daejeon to destroy the earthworms must be a period of time to sink. Sandy soil is about 1 day deep, and clay generally needs to be immersed for 2 to 3 days to reach the mud moisture level. The sediment does not become clear and muddy. The machine maintains a thin layer of water in the field, at a rate of 20-30%.
Second, the standard block, horizontal and vertical. When cutting, it should be straightened, and the length and width should be intersected into a straight body. When the cutter enters the mud, it should be perpendicular to the ground.
The base film is cut flat for easy handling.
Third, we must insert and insert basic seedlings. The rate of plant deficiencies is above 10%, especially for longer ridges and large "roofs" leaves to be filled manually to reach the levelling. To facilitate high yields.
Fourth, after the machine is inserted, it is necessary to prevent the water in the field or the heavy rain from causing the water layer in the field to be too deep, as well as floating seedlings, or invading the seedlings or submerging the rice shoots.
Third, strengthen field management:
The first is scientific water and fertilizer management. After the seedlings were established, shallow water was used to protect the seedlings, and chemical herbicides were used to select specific herbicides for transplanting seedlings. Immediately after the establishment of seedlings, the topdressing fertilizer was applied in time, and the dry fertilizer was harvested when the field was reclaimed.
The second is to scratch the field. Adhere to enough seedlings to promptly dry the field, to control the seedlings several times, control the day of delivery. In case of rainy days, it is necessary to ditch the fields.
The third is to prevent and control pests and lodgings. Focus on the prevention of three generations of rice stem borers, rice cultivars and stripe leaf blight. Do a good job of drying up the field and topdressing potash to prevent lodging.
