Lemon oysters are a good tree species that are easy to grow into raw materials for a long time, and they are also trees with higher economic value. The oil evaporated from its leaves can be used as raw materials for food, chemical industry, medicine, etc. Although its wood is susceptible to insects, it is hard and can be used as a variety of materials. Once it has been preserved, it has a wide range of uses. The cultivation techniques of its fast-growing raw materials are described below:
First, seed collection
Before and after the beginning of the winter season, the trunks of tall and straight trees with 10 to 15 years of age, no pests and diseases, and bark gray were selected. After harvesting for several days, the seeds were collected for use.
Second, the site preparation
Choose a fertile semi-sand paddy field that is far from the village, where no livestock can walk, and which is slightly sticky. After the late rice was harvested, the taro and field weeds were eradicated and dried and burned. Subsequently, the ploughshare was irrigated, and the ploughs were reclaimed after 3 to 4 days, and 30 kg of superphosphate, 10 kg of potassium chloride, and 3,000 kg of manure were used as the base fertilizer. The nursery must do three plows and three plows. After the puppets are flattened, they are flattened by hand, and then the water is drained. When the sun goes to the edge of the field, there is a slight crack in the chicken feet. The width of 1.7 meters is wide, the width is 34 centimeters, and the height is 20 centimeters. After the smashing, the mud from the sewers was then leveled and smoothed with a wooden board. The next day, a 1.7-meter-long, 8-cm-wide, and 5-cm-thick ruler was used to nail a circular flat-top wooden peg with a height of 0.6 cm and a diameter of 1 cm. Each nail was nailed every 8 centimeters. About 16 or so, there are 16 seed holes in the press. Then use a knife to cut the depth of 17 cm with a ruler, and then cross-cut according to the specifications, it can be made into 16 nutritional bricks.
Third, sowing
Prepare nutrients and bricks immediately before "Little Snow" and sow seeds. One seed per seed can be placed. After seeding, mix the soil (fired soil 1/3, fine sand 2/3 and mix well) to fill the seed holes. Then Sasha fills the cracks cut with a knife to facilitate the separation of the seedlings. Afterwards, spray water every few days depending on the weather, keep moist, and emerge after 6-8 days.
Fourth, nursery management
When the seedling height is 3 cm, fertilization begins, 1500 kg of mucous water is applied to the mu, and then the fertilizer is applied 1 to 2 times per month, and 2000 kg of mucilage water is used. When the seedling height is more than 17 cm, fertilization can be stopped and waiting for transplantation.
V. Pest Control
The diseases of lemon borers mainly include canker disease and seedling stalk rot. Once the diseased seedlings are found, they should be immediately removed, sun dried and burned, and 1:1:100 Bordeaux mixture should be sprayed on the base of the disease-free seedlings, spraying once every 5 days. Spray more than 2 times. The main pests are termites and red-footed green beetles. Termite prevention and control can be trapped by termite drugs and soil disinfection; red-legged green beetle injure seedlings and young trees, and can be sprayed with 90% crystal trichlorfon or 80% dichlorvos emulsion 600 times in seedling stage.
Sixth, transplanting
Before and after the "Spring Equinox" of the following year, there was plenty of rain, and the soil in the mountains began to grow. Around September of the first year, the first hole was dug into a square hole of 0.7m to allow the soil to be fully weathered and white, and the soil was filled with soil before the "Spring of the Spring" in the following year. The seedlings were then transplanted into the hole along with the nutrients, one for each hole. About 100 to 200 acres of planting. If there is a drought after planting, watering can be done once.
Seven, picking leaves
Every year in the summer and autumn, after the lemon pods are planted, the adobe will be ploughed, and if it is dug into ladders and fertilized, it will be easier for forests to grow. Generally more than 200 acres of planting, can be cut in three years of tree age, about 3 meters high on the trunk cut picking leaves, which is a special forest for leaf collection. If the acres are planted under 100 plants and the forest is taken into consideration, the trees can be cut once every 7 years or 7 meters. After the autumn and winter, when the leaves are collected once, the oil yield is high.
