Folding knife, a kind of knife, can be folded. The folding knife is mainly connected with a knife body which can be rotated into by a pivot assembly at the front end of the handle. The knife body is provided with a safety buckle relative to the side of the knife body, and an elastic strip relative to the back end of the knife body. The back end of the knife body is provided with a stop part and a stop concave part which can be butted by the elastic strip, and the safety buckle has a tilted elastic buckle part, The elastic strip is arranged in the holding chamber of the handle, one end of which is fixed, and the other end of which is connected with the stop part of the tool body, so as to provide the thrust to assist the rotation of the handle when the tool body is rotated out of the handle, In addition to the simple semi-automatic operation mode of turning out and positioning by using the elastic auxiliary push knife body, the overall thickness of the folding knife is reduced by the refined and simplified structural design, which is convenient for the collection and carrying of the folding knife and makes the operation of the folding knife easier. folding knife,folding knife kits,folding chef knife Shangqiu Zhengtu Hardware Technology Co,.Ltd , https://www.ztlighter.com
Second promotion: Tomato seedling stage and harvest period should be heavy topdressing to promote its growth and development. When the first ear fruit grows to the size of the walnut, it is necessary to quickly apply the quick-acting fertilizer 1-2 times, generally applying a concentration of 30% human excrement or 5% sulfur compound fertilizer leaching solution to ensure that the plant does not lose fertilizer. After the young fruit enters the expansion, in order to meet the growth needs of the plant and avoid the later de-fertilization, the method of diligence and fierce protection should be adopted. Generally, the human feces or 5% sulfur-containing compound is applied at a concentration of 40% every 10 days on a sunny day. Fat leachate.
Three sprays: Tomatoes not only absorb nutrients from the soil from the roots, but also absorb mineral nutrients from the leaves to promote the development of fruits and seeds. Therefore, during the fruit growth period, especially when the continuous continuous rainy season can not carry out the soil topdressing, the 2-3 times of foliar fertilizer should be sprayed, and the biochemical organic liquid fertilizer can be sprayed 300-500 times, and the chelating multi-component composite micro-fertilizer 500 can also be used. Spray with double liquid to improve the quality of the tomatoes.
Four bogey: Tomato topdressing avoids the soil in the case of wet and noon high temperature, and avoid excessive concentration of fertilization. Concentrated fertilization tends to make the plants grow long and produce fertilizer damage; fertilization in the soil is easy to cause physiological diseases such as falling flowers, defoliation and fruit drop; fertilization under high temperature conditions, the water evaporation of the leaves of the plants is large, which will affect the exertion of fertilizer efficiency. In addition, the fertilization time should avoid the high temperature period, preferably in the morning or evening.
Tomatoes are very sensitive to fertilizers. When topdressing, you should master the principles of “one control, two promotion, three sprays, and four bogeyâ€. One control: During the period before the tomato is planted until the fruit is set, it should be seen that the seedlings are topdressed and the amount of topdressing is controlled. If the topdressing is too much and too concentrated, it will easily cause the plants to grow up, and even cause the flowers to fall. Therefore, in addition to the serious shortage of plants, it is generally necessary to control the amount of topdressing, and slightly apply dilute or biochemical organic fertilizer.
