The light of joy. The soil is not so demanding as to be saline-resistant, fat-resistant, drought-resistant and water-resistant. Low-altitude soil may not contain more than 0. 2 per cent of salty soil, which is suitable for fertile, well-drained, neutral or micro-acid land cultivation, and is not suitable for cultivation in strong alkaline, visceral, paddy and marsh areas。
Plantation techniques
Reproduction with seed or piping。
Seed reproduction: good varieties are available to harvest big, colourful, disease-free, mature fruit, which is immersed with 30-60°c warm water, seed, washing, drying up. Wet sand (1:3) is applied before seeding, and sprung at 20°c temperature, until 30% of the seed is white or immersed in water, 24 hours a day and night before planting. Spring, summer and autumn can be planted, mainly in spring. From late march to early april, it was broadcast at a distance of 40 cm, at a depth of 1. 5 to 3 cm, with soil of 1 to 3 cm, and when the seedlings came out of the soil, attention was paid to the water. Saplings are 1. 5 to 3 cm tall, weeding is done once in the pine soil and then every 20 to 30 d of the pine soil. 6-9 cm high, at 12-15 cm long, 150-180,000 per 1hm2. In order to ensure the growth of the seedlings, a combination of water recharges in may, june and july, 40 cm should be removed from the ground in a timely manner, and the side buds should be grown in parts, which should be 60 cm tall, so as to accelerate the growth of the main stem and the upper side branch and, when the tree is 0. 7 cm thick, it may move out of the nursery。
(b) cultivation: on a good mother's plant, a thick 0. 3 cm, above the wooded one-year branch, cut into 18-20 cm long slots, immersed with 100 x 10-6 α-acetate in small bundles in a basin, and then cucumbered with a 6-10 cm slope in a ditch。
Field management
Weeding was done once in the five, six and july plantings, and in late october-early november, sheep dung, fertilizers, pies, etc. Were used as base fertilizer, followed by urea in may and phosphorous in june-july and potassium compound. In the autumn of the year, the larvae was formed and three to five people were chosen to be the main branch in the upper part of the main business, and it was shorter around 20 cm, and shorter as a bone branch at 20 to 25 cm when a new branch was launched in the second year. The 3rd and 4th year continues to be expanded using long branches on the bone branches, along the same lines as the 2nd year method, to build up the tree coronary. After 5-6 years of integration into the adult tree stage. Adult trees are trimmed every spring, cutting dry branches, cross branches and root twigs, leaving them in the summer, cutting out long branches, sick branches and needles. Comprehensively trim the tree crowns in the autumn and select a good branch of the result。
Pest control
The disease has a black fruit disease, which affects buds, flowers and green fruit. It can be sprayed with 1:1:100 bordo during the outcome period; 50% of the distillable typhoid powder 600 times the fluid is sprayed immediately after the rain, which works better. Root disease, with 50% tobuzin 1000-1500 or 50% or 50% more than 1000-1500. The pests have hyenas, which can spread 50 per cent of svd 45kg/hm2 on the ground of the garden when it becomes plume in winter, and remove maggots from the ground, water or soil during autumn winters. In the spring, it is possible to irrigate the pine soil, destroy the sources of the insects killed by the winter sound, and in mid-april 5% of the severine powder (1 kg to soil 5-7kg) was sprayed on the ground of the garden, killing the winter worms and treating trichlorfon 800-1,000 times the liquid. There's also vermin, dictum, etc。
A small shrub with leaves for eggplants, also known as gills, dog nipples, etc., is a famous fruit-seeing plant. The flowering period is from june to september, and the fruit period is from september to october. The leaves, roots and fruits can be drugged, and the roots of the plant can also be made into a field view. The range of adaptations is broad and less demanding for soil and is resistant to drought, infertile, saline and sandy soil, so that it grows best in a well-ventilated sandy border. The main elements of their cultivation techniques are:
Reproduction is often carried out by adhesion by:
1. When the nursery area has been fully prepared and the nursery area has been tumbled, each acre is applied between 1,500 and 2,000 kilograms of base or 100 kilograms of fertilizer, flattening the compartment。
2. The pick-up plugs pre-spring, combined with the trimmed sapling, collect the plugs and cut them into 10 to 15 cm long ears。
A 24-hour leaching bar with root powder. The seedbed opens a ditch at a distance of 30 centimetres, at a distance of 5 centimetres, and is inserted at a distance of 5 centimetres。
Field management 1. Weeding is done in a timely manner to prevent weeding and to compete with plants to spread pests and diseases. Following fat. Hair and fertilizer, with a long period of fertilisation, etc. Fertilizers are applied two to three times in the long run to promote seedlings, rods and fruits. 3. Cut the whole branch. The branches of the twigs are strong, the new branches are growing, and they cut the old branches before the spring starts early every year, cut the long branches in summer and cut the old branches and the sick branches in autumn. The whole branch reduces pests and pests, increases ventilation and reduces nutritional consumption. Newly planted saplings will top the main stem at 60 cm height, with three to five branches selected. In the following year, the selected 3 to 5 side branches were reduced back to 30 cm, forming the first tree crown. Next year, it will be cultivated to form three-storey tree canopies, increasing the number of broccoli. If you make a basin view, you can cut and cut the twigs before the spring of the second year, and the next year will produce flowers. 4. Water management. Drained water should be discharged in a timely manner in accordance with local conditions. 5. Disease control. Chrysotile diseases are mainly black fruit and root causes, mostly in the rainy season。
"drugs grow small knowledge - the method of cultivation of the platinum." when black fruit disease occurs, buds, flowers, fruit turn black, red slime is found in the humid conditions. Bordeaux (1:1:200) or 100 times more than 50% more fungus at the onset of the disease. When the root causes of the disease occur, the base of the disease becomes black and decomposed, the leaves on the ground turn yellow and the whole body dies. The strain found should be removed immediately and the soil around the quintozene strain should be treated with lime or 70% quintozene. In the early stages of the disease, 50% of the polybacterial spirit can be treated with 100 to 1,500 times the liquid root。
