Chestnuts are also known as twigs, twigs of twigs, twigs and twigs, and twigs of gray hair. Leaf intersemble, elliptical or long elliptical needle shapes, edges of sawn teeth, dentures, backs sealed by grey white star hair. In may-june, flowering, monochrome, homogeneity, straight and long, and the female is born in the basic male choreography. The total spherical form, the long stings of the twigs, matured in september, was slightly yellow, with two more types of brown nuts (tits) and two more twigs in each twig: one is a twig, the twig or bush, and the nuts are smaller. A cone, a wood, with only one grain per total, and a cone-shaped top of the bottom, can be eaten。
1. Growing habits
Chestnut is a warm temperate zone and subtropical tree species, which are widely distributed in the northern and southern provinces of the country, ranging from north to south-west to sichuan and yunnan. Photos of light, adaptable. Southern varieties are resistant to wet heat and northern varieties to dry temperatures. On the sand or gravel border, which is deep, wet and fertilized, the soil is growing well, while the fertile soil and the clay soil of the plains are growing poorly and have low yields。
2. Reproduction methods
Chestnuts tend to breed by sowing, and they can grow good varieties by mating。
(1) sowing
The seeding took place in september-october, piled in total, ripened, waiting for most of the seed to crack, spread the seeds, select the full, full-filled seed, and accumulate sand in the shade. Autumn broadcasts took place in october-november, and spring broadcasts took place in mid-february. The sown ditch is open at a distance of 25 centimetres, with 10 centimetres of land on the spot, and the seed is scattered across the ditch and the soil is covered. Inoculation at seedlings can promote seedlings up to 40-60 cm a year. In the following spring, “blank” from the root neck would allow the main work to be straight and well-established, and normally two years of seedlings could be transplanted from the nursery。
(2) marriage
In the case of fruit-planting, it is necessary to be married, and to be made of gills made of twigs or shrubs, and to choose a single line of good varieties, to be cut before budging, to be stored in a cellar of wet sand, and to be ceded, incarnation or plugged upon the beginning of the flow of sap or the beginning of a leaf. After delivery, the transplant is carried out the following spring。
3. Cultivation management
(1) planting
And the twigs are thick, their roots are deep and developed, and their crowns are spread out, and they are planted only in the right place. Chestnuts are in me; the country has a long history, like dates. The script of scripts writes: “the qin tree, its people and thousands of people.” the queen of xijing says: “the qin is in the forest.” the san qin qi said, "the garden is shaking." and the gardens of the ancients are adorned with chestnuts for viewing. Chestnuts are now more common in family homes。
The tree is designed to produce two or three full years of seedlings with roots, to dig large holes, to produce base fattening, to plant the roots in a manner that stretches, does not make fists, and to fill the earth with layers. Then water and earth. The plant should not be too deep, as the ground has just surfaced. The planting period is suitable for spring planting or autumn planting。
The management of post-plant water fertilizers is closely related to the growth and growth of the chestnuts and the flowering of flowers. They grow faster in the long term, require more water and are often watered, which should be combined every time they catch up. The first one can be performed three times in a year, the second in late march and early april, mainly with nitrogen fertilizer; the second in mid-june, mainly with phosphorus fertilizer, with nitrogen and potassium fertilizer; and the third in mid-august, with potassium fertilizer, with nitrogen and phosphorus fertilizer combined, which is more important in the flowering outcome period. Fat-trapped species are dominated by quick-effect fertilizers such as ammonium sulfur, urea, and ammonium phosphate. The courtyard is based on natural happiness, small trees, uncentrified trunks, 3-4 branches and a good ventilated ventilator. It is organized at a height of 1 metre above the ground, with three to four strong, evenly distributed, medium-arranged branches being selected as the main branch, which is tilted 50 to 60 degrees outward, following the break below the cut. Of the branches that will follow from the main branches, two or three of the branches that will grow from distance to strength will be short, 60 to 70 centimetres each, and will grow into side branches. The tree shape can be formed in 3-4 years. In order to achieve a robust parent branch both inside and outside the canopy, the chestnut tree is expected to reach the end of its final term. It is important to maintain a balanced distribution of the outer branches of the canopy, so that they are not too dense, so that the internal ventilated branches are well ventilated, and to reduce nutrient consumption by cutting them early. They cut long branches, overlapping branches and insect branches at all times。
(2) pest control
The main pests are chestnuts, chestnuts, chestnut worms, etc., for the purpose of pestilence and seedlings; chestnut bees for the purpose of twigs; and chestnuts and black stars for the purpose of drying out branches. (c) prevention and treatment: caterpillars and aphids can be sprayed with 1,200 times dichlorvos, 80 per cent of dichlorvos; chestnut bees can be treated with trichlorfon or pine per 1,000 times as a pest to be eradicated. Tin oxen used diarrhea 1 and light diesel 0. 5 copies, and cotton pores. The disease is mainly dusty, with 0. 5 per cent equivalent of bordeaux sprayed three times after gestation and one every eight days。
4. Watch
Chestnut leaves are so thick, so strange, so cute. Open spaces in the courtyard can be planted alone. Adaptive, easy-to-plant management, one-year, multi-year harvests are our special stem fruit tree species, popularly known as “iron crops”. The fruits are rich in nutrients, tastes delicious, and can eat raw foods and fried foods to produce cans of snacks. Chestnut shells are medically available。
