1 plantation and management of early childhood trees
1. 1 plantation
1. 1. 1 high standards of ready farming. On the hillside, ladders were built, flatland lowlands were planted, and water, soil and fatty “3s” orchards were built. Digged 80-100cm deep, fertilized foot, 30-40kg organic, 1kg phosphorous and 1kg lime, mixed with topsoil, and returned to the base of the inverted pan, 30 cm above the ground ... Before planting the plume。
1. 1. 2 choose a good seedling. The choice is to use local prunes and poignant peaches as saplings and seedlings that are married to the mother tree of san hua。
1. 1. 3 mastery of the period, reasonably secreted. After the winter-size cold leaves were used, 667 m2 of 50-60 plants were planted when the sprouts began。
1. 2 strengthening of larvae management
1. 2. 1 enhanced post-plant fertilizer management. Stuffed water, shampoo, moist soil maintenance, rooting and increasing survival。
1. 2. 2 when the trees are alive, the principle of fertilization shall be `involved'. Cultivation takes place once a month with half-septic + 0. 1 kg of urea per plant, followed by one in january, april and july of each year with a combination of 1 ~1. 5 kg of potassium sulphate plus 0. 2 kg of urea per plant, combined with leaf fertilization。
1. 2. 3 improved soil environment. The weeds are treated in a manner that increases soil organicity by quenching them once a year。
1. 3 focus on trimping and breeding productive tree crowns
Cultivation of early productive crowns provides a good basis for high-yield quality fruit. Pear pack techniques and when are the bags of plum trunks not visible, tend to cause sprawl, chaos, influence light and infestation. It is therefore necessary to repair the branches in a timely manner. The three branches are naturally happy. Set a pole at a height of 50 to 70 centimetres, sprouts at 5 to 10 centimetres, with a growth of 120 to 40 centimetres, and shorter growth at 30 to 40 centimetres, fostering three pillars of 120o each. The sprout is followed by a sprouts of the plentiful canopy, so that the branches grow evenly and grow as quickly as possible。

2. 1 growing a strong parent branch
2. 1. 1 fertilization after fruit. The results of the trivalry are mixed with those of the short branches, which are many and small, and few and large. In order to grow a strong short branch of fruit, and a strong bouquet of flowers, the parent branch must be fertilized once in the first half of the month following the harvest, so that the tree position can recover as soon as possible, with early stubling, good summer and autumn as the fruit branches of the following year, early falling of the leaves, and the promotion of bouquets. Fertilizers were applied mainly in nitrogen, phosphorus, potassium and organic soil。
2. 1. 2 croping. Zihua li trimesters are timed, usually starting with fertilizing after the fruit. Usually long branches are short 1/3 and medium branches short 1/5. Cut or cut off, promoting the emergence of more side branches as a consequence of the following year. Cutting out the weak branches, the dead branches, the long branches and the sick branches, making them a happy, productive tree crown。
2. 1. 3 water management. Water conservation and drainage in a timely manner. A drought following the harvest requires water to be pumped early in the summer and autumn. In the long rainy days, attention must be paid to drainage。
2. 2 strengthening winter management
2. 2. 1 motivated sanhua li to fall in winter leaves. San hua li is a tree of fallow fruit, and only light leaves can produce flowers. To push san hua li to fall all the leaves in front of the snow, so that the leaves will flow back to the branches. To ensure that tree nutrients accumulate adequately and that flowers are improved. Specific measures include a combination of winter and clean gardens, cutting down horizontal roots under water lines at the edge of the canopy, and controlling water for fattening and causing leaves to fall. A few days after sunbath, the soil fertilizer can also be filled with a suitable amount of lime and phosphorous fertilizer to induce the filling to rot. If most leaves remain unleashed before the snow, the thicker leaves can be sprayed with ethylene, at 50 kg water plus 40% ethylene 20-30 ml. Or, in combination with the winter clean-up park, disinfected, with 300-500 oxidized copper chloride solution sprayed in the trunk and leaves to induce them to fall. The leaves can then be beaten with bamboo whips。
2. 2. 2 fertilisation in winter. The fertilisation of zhang hua li during the winter period has the effect of boosting the growth of buds and raising the quality of flowers in order to increase the rate of production, increase the fruit and improve its effects. The application should be dry, dominated by organic fertilizers, with appropriate additions to phosphorus and potassium. Early ripening occurs in the winter months before and after the winter, and late ripening occurs in the winter before and after. Promote flowering the following year。
2. 3 plumbing fruit, appropriate berries
2. 3. 1 the pollination process shall be carried out by mediums such as wind, insects, etc. Therefore, bee-laying or enticing insects should be used during the flower season to improve pollination quality。
2. 3. 2 prevention of burning and plumes. In the event of high temperatures in the yang era, water shall be sprayed in the morning and evening in order to prevent the burning of the flowers; if the rain rains continue, the flowers and trees shall be shaken immediately after the rain, and the water of the florist shall fall, and the water of the florist shall be prevented。
2. 3. 3 moderate agitation. Snitching is one of the key measures to nurture the zhanghua li. Zhang hua li's long-leaved branches have produced more results, resulting in low yield and low value due to insufficient nutrient supply. To be competitive in the market, it is necessary to implement moderate fruit-cutting and to make the fruits large and attractive。
2. 4 cumber and fattening
It's an inter- and extra-synthetic application. When the fruit is so big as soybeans, the root fattening is appropriate for quick-effect fertilizer and quick-impact nitrogen. Spraying can be done with 1,000 times more liquid than trivalent lig or polyester and with 50 kg water plus urea 0. 1 kg plus potassium phosphate 0. 1 kg。
2. 5 collection
A timely harvest is a key link in ensuring the production of the li park, ensuring fruit and quality and raising economic revenues, and the final link in management of li park. The maturation period is inconsistent, and care must be taken to collect the fruits in batches, to collect them in due course, to ensure that the fruits are high-yielding, high-yielding, high-quality and easy to store for sale. The treatment of citrus worms during harvest is to be determined on the basis of their use, market requirements and storage. In the case of local sales, fresh food, processing, etc., maturity should be slightly higher; long-distance transport should be slightly lower. The rest will continue to grow at a time when moderate maturity and larger fruits will be harvested. When harvesting, hold the fruit with your hand, then twist it slightly with your index finger and connect it to the branch, so that the branch is not broken so as to affect the next year's production, and so that mechanical damage is avoided。
3 strengthening integrated pest management
The main diseases of daego sanhua li are gel, powder, anthrax, coal smoke, etc. The main pests are aphids, mites, gold turtles, moths, oxen, shellworms, moths, bees, moths, moths, etc. Throughout the production management process, care is taken to observe the occurrence of pests and diseases and to prevent them in a timely manner. Preflowers can be sprayed with 1,000 times liquid oxidation and 800 times liquid dicofol to combat aphids and mites. For curvature periods, 2. 5% b-cyprim emulsion can be sprayed with tree crowns and floors to prevent and treat prune bees. Aphids can be treated with 800 times liquid oxidation fruit and gold turtles, moths, moths and moths with 800 times liquid trichlorfon or 1000 to 1,500 times liquid kung fu. Powder, anthrax and coal smoke can be combated with 1,000 times liquid m-45. After picking fruit, 50 times the liquid diarrhea can be injected into the oxen's cavity to combat it. After winter, 600 times liquid oxychloride can be sprayed (limited to winter spraying) and after scraping the glue can be sprayed to prevent the disease. Copper-containing pesticides are restricted to winter use in order to prevent the production of fallow leaves, and sulfur-containing pesticides are banned during the broach period to prevent the fall fruit。
