It was originally a fruit most found in the south, but it is now marketed in the northern region because of the advanced transport and scientific and technological developments. It not only produces delicious and attractive fruits, but it is also a flower-looking tree that grows a tree in its own courtyard, which will be effective in raising the beauty of the courtyard and making it beautiful。
Cultivation tends to be more intensive because it is the least costly and the most cost-effective way, but it is also possible to plant its own flowers。
I. Tests for throat resources
Quarrying: it usually takes 15 years for the flower to grow, and the fruit tree to grow has a clear difference in size and age. The ripening period is from late october to mid-november, during which collection should be carried out in such a way that too late the fruit is easily eaten by animals and cannot be collected. After the return, the fruit shall be stacked for three to five days, pending the softening of the bark. The sand mixed with the fruit washes the meat, drys the seeds with fresh water, and the seeds and sands are evenly mixed at a ratio of 1:3 and accumulate. Seeds weigh approximately 800 grams per 1,000 grains, with an acreage of 30 to 35 kg。
(b) sowing in the field: the nursery shall be suitable in the sandy sandy soil, which is in the sun and well drained. The planting is preceded by deep excavation of the nursery and 3 per cent of the raw lime. The bed is 1. 2 metres wide, the bed is 20 cm tall, the bed is nuanced, the stone, weed is removed, the edges and the walkways are open and the bottom is flat and water is not available. The seeding took place in early march and was on-demand and on tape. The range is 10 x 25 cm, the distance of the line is 30 cm and the depth of the sown ditch is 8 to 10 cm. Decreasing bread fat first at the bottom of the ditch, then a layer of five centimetres of yellow soil covered with base fat before planting. The seed is then covered by an additional 2 cm thick yellow soil, which helps to reduce weeds among seedlings, promotes seedling root growth and lasts a layer of straw to keep them wet。
Ii. Strengthening technology for the piece
Embroidery: the stage of the plasticization of the end-of-age tree, in order to rationalize the configuration of the main branch, the secondary branch and the branches, and to give them a proper orientation and location when they are sprouts, so as to concentrate on the cultivation of the strong branches and the secondary branches. Growing trees can reduce the number of branches by plastering them, so that the clusters of results are strong and conducive to results。
2. Cutting: zirconium has the properties of a spinal branch and is denser in stratums, resulting in a small number of twigs, small numbers of insiders and insufficient light. Thus, the dense branches, the weak branches, the overlapping branches, the cross branches, the pyrotechnic branches and the surplus branches or the decaying branches of the tree canopy are to be removed。
3. Deletion: the result is in areas free of frost, in order to regulate the years and years, to ensure that the years are productive and steady, and in the period of the fruits, the end of the year is to be omitted. The ratio of outcomes to growth branches is usually 3:2. If the growth branch is too small, it must cut off some of the raisins of the result branch, so that it can be produced the following year. If the branches of the parent and the result branches are weak, they can be removed from the base and one or two leaves can be retrenched if there is some space or if the cut is empty。
Iii. Plumbing management
And the luminous lumber cut off from the branches of result and the luminous luminous ear, and cut off the whole luminous ear; and the luminous ear accounts for 20-30 per cent of the whole tree, depending on its direction。
Out-of-the-ground fattening, which is nutritionally deficient to avoid large flowering, is repeated; 0. 2% urea or potassium phosphate solution is sprayed every three days。
In order to increase pollination rates, it is possible to spray dry or inter-horticultural water in the morning。
Iv. Pest and pest management of euphoria
The main pests that are common during the formation of the parent branch in the summer are the hazards of red spiders, yellow spiders, tailworms, yellow caterpillars, oxen, ostrich butterflies, pear-eating heartworms and branch decomposition, leaf-borne diseases, etc。
The leaf-borne diseases are aimed at enhancing the management of fertilizers, improving drainage and irrigation facilities and improving the resilience of trees. During high-temperature and rain in the summer, leaf sprays of phenometha or molybdenum esters were used to combat folic scabs, anthrax, etc., and pests were treated with 2. 5% kung fu or 2,000 to 3,000 times the chlorine poisoning. (b) the conversion of 77 per cent of coronary copper to a paste of 1:2 with wettable powders and plant growth regulators, and the painting of trunks once every 4 to 5 days, three times in a row, to prevent the dry decomposition of branches. The months of april-may and august-november are peak periods for red spiders and yellow spiders, which are treated with adimethyl amitraz or biphenyl esters。
The tailworms occur twice a year, and the larvae are community-based, capable of being manually hunted, and yellow caterpillars are treated with 2. 5 per cent kung fu or 2,000-3000 times the chlorine poisoning. In mid-june-august, the sky cow lays eggs on the base of the branch, the post-laying part of the surface is the word “chamber” and the larvae has just been laid and, if the larvae has sprung into the branch, 80 per cent of the diarrhea cream is injected with a syringe, 50 to 100 times the fluid, and the hole is sealed with clay。
Before the larvae bag, 2. 5 per cent of kung fu or 2000-3000 times more was sprayed or attacked with red sugar, 2 with vinegar, 10-20 with water, with a small amount of white wine and 90 per cent of the trichlorfon crystal system entrapd with sugar vinegar, and against ash butterflies and pears。
Spraying growth regulators promote the development of buds and increase the rate of neutrons, which should be sprayed with cytosyte 80-120 times the fluid or 0. 1% aluminum。
