(b) the greening of haemorrhagic plums by the chengdu gardens: sowing, seeding, strangulation, adhesion; more practical methods are grafting, interpolation
1. Elephants are suitable for breeding in branches, such as peaches, peaches, apricots and lees, and they choose to grow strong, insect-free, flower-rich and long-lived seedlings, which need to be selected through constant observation, so that they can evolve and evolve. It's better in 2-7 centimetres in diameter. It's a straight pole. It's soft. It's 30-40 centimetre high trunks. It's 80-100 trunks. It's better to get married before spring does not gestation。
2. Ellipse piping is only suitable for a sprawl-type ellipse plume, which is not easy to live; the piping is 10 to 13 cm after fall, cutting the ear, breaking up the soil of the nursery, pouring the water, and then putting it in a hot shed for winter, checking for roots around march of the following year, and distributing them, using some root agent。
It is also possible to sow breeding by sowing water for three to five days, then sowing it into the field at a distance of 30 *50 centimetres per acre, planting 10 to 12 gramps per acre, and seeding of algae plumes, which is sold at my base。
Day-to-day administration of elie mae:
After the seedlings were planted, the first flat was built with the aim of growing a larger and better crown, which could also be done before planting. Yeh mae grows fast, likes well-silent, soil-rich land, cold-resistant, water-absorption, and low-lying water is not planted. The fields are well drained, clay, sandy soil and yellow soil can be planted. Longer-term use of compound fertilizer is applied every 30 - 45 days, summer temperatures are not applied, and the better fertilization season is the peak of 15 - 27 degrees celsius and can be used for application in winter. Water will be watered, weededed, as appropriate, will not be used as herbicides and will be stopped after winter。
Pest control
Among the common diseases of greening the chengdu gardens are black spots and cancers。
1. Patterns of the occurrence of black spots: black spots mainly affect the leaves of the leaf, and when the leaves are injured, they have brown spots, which spread into the veins, which can be connected to large spots, often with black brown molds, and late leaves with dead leaves. Black spots are transvestite fungi infections, with bacterial filaments rising in winter, and next spring they produce saplings, which are transmitted by air and rain, infested from the pellets, which can be repeated during their growth and during their peak in june and september, which can cause the planting of leaves to be significantly removed when the damage is serious, thereby affecting the growth of the plant。
Prevention and treatment methods: enhanced management of hydro-fertilizers, improved resistance of plants to disease by the end of the autumn, clean of leaves and central burning in the spring pre-sprouts, 5-perimetre thiomers of thiomers are sprayed once, and in cases where 80 per cent of the dyssens can be humid particles can be sprayed 700 times, or 70 per cent of the dyssey manganese thigen 500 times, every seven days, three to four consecutive sprayings can be effectively controlled。
The disease occurs mainly in the root and sometimes in the main and side roots, with the affected areas forming tumours of different shapes and sizes, the first-born tumours of grey or flesh, the softness of the surface, the smoothness of the surface, the gradual transformation into light brown, the physical hardening of the tumour surface, and the roughness of the tumour surface with net cracks. The fungi is transmitted by moisture, adhesives, grafts, subterranean pests and enters the tissues from the point of deterioration. High-temperature, high-humid periods are more conducive to plant morbidity。
Methods of prevention and treatment: quarantine measures should be strengthened to prevent the introduction of disease-bearing seedlings and the timely prevention of all forms of subterranean infestation, the removal of tumors with disinfected knives, and the elimination of the bordeaux lactation tool prior to its use。
Pest breeding methods
The most common pests are aphids, red spiders, moths, shellworms, leaf jumps, aromatic wood moths, oxen etc. If it occurs, aphids can be killed by shoveling 1,500 times the fluid; 40 per cent of dicofol cream 1,500 times the fluid can be killed by red spiders; moths can be sprayed with 1,000 times the bt emulsion; leaf-killing jumps can be killed with a 2. 5 per cent enemy of 3,000 times the cream; and aromatic moths can be killed with 400 times the zinc parathion injected into the insect tunnel by sealing worm holes with mud to fumigate the larvae, or with a root application. Mundane's method is to kill; it can be used to control taifs with 500 times the green willey。
The technology for greening the gills of the chengdu gardens was published by the golden cows landing tree company。
