Plan to plant yang mei tree
I. Forest land selection and landscape。
The yang mei park is built at altitudes of less than 800 metres above sea level, with slopes of less than 45 degrees, a corrosive layer of thick, acidic yellow and red yellow border at ph, ventilation to the ph, easy to organize, easy to transport mountains, hills, hills, ill-lights and deep ground. The climatic conditions are subtropical wet monsoons. Quality and abundance are more significant under small climatic conditions with high light radiation, sufficient heat, high temperature in the spring of the winter and moderate distribution of precipitation in the summer and autumn。
The site should be adapted and completed from november to march of the following year. Smaller slopes, flat slopes of forest land, the opening of rounded slopes or ladders to dig for caves; large slopes and complex topsoils, and the digging of one metre of fish scavengers or triangles, have gradually been transformed into narrow-banded ladders in later breeding。
Ii. Planting。
When yang mei's planting time is usually starting to warm between late february and mid-march, it is advisable to choose between shade or light rain, at which point the single plant is set to have a high rate of activity. The selection of varieties should be based on a rational mix of early, medium and late-literate varieties, suitable for the planting of the species in our province. Choose a strong, root-rich, pest-free, high-quality yang-mei seedling, adding 10-15 kg of cortex fat and 5-10 kg of coke ash to the dug dens, moderate and shallow planting, and then planting small earth around the plant and timely earth cover to avoid the presence of roots. Yang mei is male and male and needs to be planted with a male plant of 1-2% for pollination。
Iii. Fertilizer water management。
Forest land can be grown for one year with raw vegetables, medicines or green fertilizers to improve soil fertility. Quick-activated fertilizer is used mainly in juvenile trees, with nitrogen, phosphorus and potassium applied in combination, with two to three constant fertilisations. For the first time in the early spring of the winter before the budding spring, the adult tree is fattening twice a year, with a plant-by-plant application of farm fat or calcium phosphate 1-2 kg; or 1 kg urea per potassium sulphate, or 15-20 kg urea. Then the earth will be covered. The second was 50-55 per cent of the annual fertilization rate after the harvest, with 10-20 centimetres of ditches being opened under the tree canopy line, kg of nitrogen fertilizer, kg of phosphorus, potassium fertilizer and 30-50 kg of fertilized soil, in accordance with the principle of multiple fertilization. The meat roots of the yang plum tree are easily damaged and the roots are avoided while digging in a ditch. Vegetable growth can also be followed by the application of noodles, i-2 times such as % potassium dihydrophosphate or % potassium sulphurate. In addition, soil improvement and the removal of water stains ensure the quality and high productivity of yang mei。
Iv. Integrative trim。
The yang mei tree is dominated by a natural circle head. The larvae are trimmed mainly in dry form and produce early and productive tree bodies. It's usually a “triple branch” natural fun canopy. This is to say, the selection of three to four strong growing branches with a balanced distribution and distance between them (about 20 to 30 centimetres) and the selection of two to three sub-principal branches or side branches on each of the main branches to make them reasonably distributed, stratificationally and basically form a tree coronary in three to five years. Adult trees are trimmed primarily to develop productive group structures, regulate growth and strong relationships and promote sustained, high-quality and high-yielding production. Intangible shears are divided into summer shears (opening angles, hearts, twists, sprouts, pulls, picks, strips, etc.), winter shears (swipes, retweaks, short cuts)
V. Artificial regulation of growth and results
1. Precautions of flowers. In the case of unincorporated trees that have been growing for more than five years, with early results and with low growth outcomes for adults, planting management has been strengthened, with multi-effects in the following march (november). The method is to remove the earth from the area where the tree canopy is projected, in order to see the roots, and to quantify the multiple effects. Scattered with about 30 times the cortex and then evened under the tree crown; or sprayed 800 pp of polypolymphs before flowering, or spring porcelain fruit, with 20 to 30 ppm aroma for chemical conservative fruit, sprayed with % % potassium phosphate solution in the first half of march, once in 10 days and twice in a row to increase the seat rate. A larvae of less than five years is not suitable for application. Soils may only be carried out once every four to five years, and leaves one to two years。
Ii. Plumbing fruit. Usually between february and mid-march, the whole tree was shrunk with too many flowers. An amputation branch of 1/5-2/5 with urea equivalent nitrogen kg each contributing to trophic stalks; or chemical lumbering with `5' 200 times or `6' 100 mg/kg during flower season. More fruit is given 20 days after the flowers are given, depending on the number of tree tectonics, which is usually left in the upper part of the crown and in the lower part, which is usually 2-3 times; it is also given flexibility depending on the tree direction。
6. Disbursements in due course
The maturity period of the yang prune is not consistent and is subject to collection in batches. Picking can begin when 20 per cent of the fruit is ripe, usually once a day or another day. The morning or evening harvest shall be appropriate in order to prevent the harvest from taking place during the rainy day or at the beginning of the morning. Yang plum fruit is not protected and is highly susceptible to bruises and should be light, light and light. The fruits are found in a basket of bamboo or bamboo with fresh beryllium or wood grass on its base and surroundings, and are taken in a suit to reduce crowd pressure. Each basket should not exceed 5 kg in order to be good, fresh and good for sale。
7. Pest management. Yang mei's resistance is strong and pests and diseases rarely occur. However, it is also necessary to develop appropriate pest observation and integrated management as a result of wide-scale seed exchange due to ecological changes. The main pests are long white moths, leaf moths and bag moths. The main diseases are brown spots, cancer and swelling. Methods of prevention. Strengthen plant management and enhance tree position; cut sick and dead branches in a timely manner; clear winter gardens, clear leaves and weeds and focus on burning. Medicines: cancer swollen disease, which can be removed with a fast knife after the spring and autumn seasons, then decontaminated with 50-10 times the antibacterial agent 402 or 200 ppm of agro-chain carcinogen, 15 days later. Brown spots, with 50% more fungus 500-600 times the fluid or 70% more methyl tobuzin, or 65% more than 600 times the nectar, sprayed with tree crowns, 7-10 again and 2-3 times more。
