First, Putian choice and processing Choose a garden or garden with flat terrain, fertile soil, convenient drainage and irrigation, sunny leeward, and easy management, establish a permanent paddy field, and insist on increasing farmyard manure and fertility. 1. Make a bed of land. The single-frame type seedbed is made of 10 to 15 meters long, 1.2 meters wide, 8 to 10 centimeters high, not to get out of bed, 8 centimeters high, 10 square meters per acre Honda seedbed; open and closed seedbed width 1.4 ~1.6 meters, two beds separated by 70 cm channel. 2. Bed soil fertilization. Apply 10 kg of farmyard manure and 0.1 kg of diammonium per square meter, spread it evenly on the surface of the bed, planer 3 times, fully mix with the 10 cm soil layer. 3. Bed soil acidity. The specific acid-adjusting method is based on bed soil acidity alkalinity every 10 square meters with strong agent (2.5 kilograms) mixed with 15 kilograms of fine soil, scattered into the bed three times, with a planer 3 times mixed with 10 cm soil layer. 4. Soil disinfection. After acidifying the seedbed, the bottom of the planting day should be filled with water. The standard is 5 to 10 cm. The soil layer is saturated. After the water is fully infiltrated, 2 ml of transplanting spirit is used per square meter, 7 kg of water is sprayed evenly on the bed. On the surface, one spray finishes. Second, sowing 1. The sowing date is determined. The local temperature is stable when passing 6°C. Chengde City should generally sow before and after April 15th. 2. Prepare nutrient soil. The nutrient soil is made up of a mixture of soil, farmyard fertilizer, and strength-promoting agent in a certain proportion (custom soil or garden soil or dry soil). The structure is good, organic content is more than 2%, nutrients are complete, no pathogenic eggs, no salt , No weeds. Farmhouse fertilizers should be fully cooked). According to the ratio of 60% to 70% of land and 30% to 40% of farmyard fertilizer, it is prepared. It is sieved with a sieve of 5 to 8 mm in diameter, and then fully mixed into the soil and fertiliser in accordance with the instructions for use of the strength-enhancing agent. In accordance with the proportion of 1 kg of nutrient soil per square meter nursery, apply it evenly and mix it with tweezers. 3. The amount of broadcast. The general seedling age is 35 days, insert 4 leaf 1 heart seedlings, sow 250 grams per square meter sow seeds, sowing seeds must be evenly spread on the bed, and then use the wooden roller or other apparatus to press the seeds into the soil, let Seeds are buried on three sides. 4. Cover soil and seal grass. Cover the screened sandy loam without grass seeds 0.5 to 1 cm. Spread it by hand until it is dew-free. Use "closed No. 1" (low toxicity) 8 to 10 ml and 10 kg of water. Spray evenly on a 10-square-meter seedbed with a sprayer. Spray it once. Be sure to spray it evenly. Do not puddle with it. Do not spray it in excess so as not to cause phytotoxicity to young shoots. Other herbicides may also be used. Third, the arch cover film The arches are 40 to 45 centimeters high. Every 50 centimeters are inserted into a piece of bamboo. The film is fixed with a string of ropes. The film is tightly compacted and fixed with a bridle. Fourth, seedbed management 1. Sow until the Qimiao. Insulation moisture, promote Qimiao, intra-membrane temperature control at 28 °C ~ 32 °C, more than 35 °C to ventilate, to prevent high temperature damage to seeds, roots and shoots, to 60% emergence, spray a Qimiao water. 2. Emergence to 1 leaf 1 heart. Should pay attention to temperature and moisture, to ensure the rooting of the required moisture, the film temperature is controlled at about 25 °C, more than 28 °C to increase ventilation, open two ventilation, combined with spray water per square meter with transplanting spirit 1 ~ 1.5 ml, right 3 to 4 kg of water is sprayed to prevent blight. Spray water 1 to 2 times in this period. 3.1 Leaves 1 heart to 2 leaves 1 heart. The measures are temperature and humidity control, which are conducive to balanced growth between upper and lower levels to prevent leggy and bacterial wilt from occurring. During this period, seedlings are least sensitive to moisture, and soil moisture should be controlled mainly by dryness. During this period, water is generally not sprayed. The temperature is controlled at about 20°C. When the film is sunny during the day, the film should be fully opened. It should be covered at 4:30 in the afternoon and it should be turned on at 2 hours in the rainy day. If the temperature is lower than 10°C, do not remove the film for too long. Cause cold damage, resulting in physiological disease. In this period, if the ventilation is not enough to make the shed high temperature and humidity, the seedlings tend to grow in length, the roots become thin, and the vitality decreases, causing the occurrence of bacterial wilt. Practice has proved that the ventilation and hardening seedlings are the key measures to promote rapid rooting and improve seedling quality. . 4.2 Leaves 1 heart transplanted. The measures are moisturizing and hardening seedlings, raising seedlings and promoting pods, pouring 2 watercress and 1 watering period, and then spraying water once every morning at 8-9 hours. During the day, all ventilation is turned on, and 4 to 5 days before transplanting. There will be no frost at night. The film is completely stripped. 2 leaf 1 foliar spray can be applied to the right amount (do not use growth regulators containing chemical synthesis) such as trace element fertilizers, plant growth aids, or combined with watering 80 to 100 g of diammonium per square meter. After spraying 1% of fertilizer water evenly, spray water again. 5. Strong standards. Seedlings 28 to 30 days of seedling age, seedlings 12 cm in height, with a pod rate of 50% or more, leaves standing upright, stems flat, 100 gram dry weight 3.0 grams, 9 to 11 roots; 30 to 35 days of seedling age Seedlings, height 12 to 14 cm, number of 10 to 12, root length 18 to 27 cm, roots white, Baimian dry weight 5.0 grams or more, more than 50% with two scorpions.
