The urea fertilizer was 2000 kg, and the tiller was evenly cultivated after the fleas. In the north-south direction, the seedlings are 1 meter wide, and within the centipede, shallow grooves about 2-3 centimeters wide are formed about 20 centimeters apart. The new toad seeds will be winged, soaked in warm water of 40°C for 10 hours, and then washed repeatedly with fresh water, mixed with 1:1 volume of fine sand, and then evenly sowed in open shallow ditch, about 3 kg of pure seed for mu. . When the seedlings grew 2-4 true leaves, the seedlings were weeded to maintain a spacing of about 15 cm and about 20,000 leaves were planted.
Shed, Transplanting Sheds and Transplanting Shelfs are made of conventional one-story vertical plastic film solar greenhouses, 8 meters wide from north to south and 40 meters from east to west. The walls are made of earth. The back wall is 2 meters high and 60 cm thick. High 2.4 materials, sheds with cement columns as scaffolds, sheds with bamboo rafts for the front slope as a beam, covering ordinary polyethylene film, covered with rice straw at night. Shed with corn stalks and straw stubs on the back slope of the shed, protected against heat and cold. From early to late November, the seedlings of citron shall be transplanted in the greenhouse. Before planting, Mushi diammonium 100 kilograms, chicken manure 5000-10000 kilograms, deep-turn 60 centimeters, squeaking, flattening, for 1 meter wide, 40 centimeters wide, easy to walk into the shoots, acres planted 8-10 10,000 plants. After 10-15 days, the seedlings were moderately seedlings, and the temperature was 10°C during the day; the daytime temperature was 18-23°C during the growth-promoting period and 13-15°C during the night.
The management of the shed body and the postharvest management of planting buds will be performed after planting and planting water will be poured. The second round of water was carried out after the two scented citrons had been harvested. Before the third round of watering, 25 kg of diammonium and urea were mixed to make it dissolve with water. At the same time with 0.5% urea and potassium dihydrogen phosphate, every other week alternately sprayed on the leaves of Toona sinensis for foliar fertilizer. Every morning, we should roll up the grass on the front slope to maintain a suitable temperature in the shed. Snow cover should be timely cleaned when snowing, to prevent damage to the shed body. About 50 days after the seedlings enter the shed, the top buds can grow to about 20 cm. At this time, the first shoots can be taken. The first time only the top buds were picked and removed to promote the sprouting of buds. After picking, timely fertilization should be done. After that, when the buds grow to 15 cm, they begin picking, while the bud base retains 1-2 leaves, promoting its regeneration. Picked citron buds should be spread damp and cool, avoid packing along with the package with plastic bags, to prevent buds off the leaves, reduce bud quality. After the end of the entire harvesting period, the seedlings were transplanted into the field for laziness at the end of April. When it was prosperous from June to July, paclobutrazol could be sprayed 300 times for dwarfing, and then the seedlings could be transplanted into the shed for growth and harvesting.
