Qing Mei and Li Summer Management Points
In the summer, when the prune is harvested and the plum fruit matures, the following cultivation management measures should be taken. 1, timely recovery of green plum harvest before harvesting fruit fertilizer should be applied within a week after harvest, put the amount of fertilizer according to age, tree potential may be, a material wealth of 0.5 kg of compound fertilizer. Li Guozheng should be applied in the hard core of fruits, usually 0.5 kg of compound fertilizer in late May. Before and after fruit picking in about the first half of July, 0.5 kg of compound fertilizer is applied to the fruit. The general result is less Li Shuke. Delayed to apply within one week after harvest to ensure high output and stable production in the coming year. 2, weeding and weeding in general before and after fruit picking for a cultivator in addition to planning, loose soil 5-6 cm, and then use a mountain soil to cultivate trees, 5-6 cm thick, to prevent the mountain orchard dew root, leading to premature aging of the tree. 3, orchard grass cover only when the soil oxygen content maintains about 10%, Lee, plum root system can grow normally. After covering the grass in the orchard, soil organic matter can be increased to keep the soil loose and promote the growth of plum and plum. 4. After summer pruning, Lee and Mei should have a summer cut. The topping of the upright growth branches and other vigorous growth shoots on the inside of the canopy and backs of the tree crown can control their vegetative growth, promote shoots enrichment, and improve flower bud differentiation quality. Standing on the canopy of standing Wangzhi, in its semi-lignification, twisting the tip 5-10 cm from the base can help to reduce the growth potential, increase the accumulation of nutrients, reduce the consumption of nutrients, and have excessive branches and slim branches in the crown. Vice branches, aging branches and diseased branches were removed. The side branches that compete with the main branch, the large result branch groups and the leggy branches that can be used are pulled to 60-80 degrees with a rope, making it larger than the main branch angle, which can ease the growth potential and promote flower bud differentiation. 5, pest control leaf Note in late May and mid-July, second and third generation mulberry white locust prevention and control, can choose to use 40% of the milk emulsion or 40% speed culling EC 800-1000 times liquid spray. In addition, attention should be paid to the prevention and treatment of coal smoke. To prevent premature defoliation, improve flower bud differentiation rate. 6, anti-logging drought Lee, plum is a shallow root fruit trees, sensitive to moisture. During the May-June rainy season and July-September high-temperature drought or typhoon storm, trenching drainage and drought protection should be done.
ULITE DIY Inverter Welder has comparable good price. The MOSFET design in the machine could save much cost. The PCB board is single board or three board.
Advantage:
1. Smaller size, light weight, and high efficiency with low consumption(TIG Series).
2. When used for MMA, easy to get arc started, without cohesion between work piece and stick, suitable to acid, alkaline and stainless steel sticker.
3. Stable under continuous condition, this machine can working normally when power network fluctuates among ±20%, compensate the voltage if there`s any fluctuation.
4. Good welding performance with high strength, especially thin sheet metal.
5. Suit to stainless steel, alloy steel, carbon steel and other nonferrous metal, applicable to the industries decorating, furniture, vehicle and hardware, and etc.
