Vegetable spray micro-fertilizer to put six off

<

Practice has proved that it is a cost-effective application method to spray the vegetable leaf surface after diluting the micro-fertilizer, but the following "six levels" should be put in the spraying process:
The concentration is off. The concentration is suitable to receive good results, and the application concentration is too high, which is not only useless, but harmful. Generally speaking, suitable spraying concentrations of various micro-fertilizers are: boric acid or borax solution 0, 05---0, 25; ammonium molybdate solution 0, 02%--0, 05%. Zinc sulfate solution 0, 05--0, 2%; copper sulfate solution 0, 01--0, 02%; sulfuric acid to iron solution 0, 2--1%.
The period is closed. The period of spraying micro-fertilizer must be determined according to different vegetable varieties and different micro-fertilizer varieties, and it is generally suitable to spray before flowering.
The dosage is off. The amount of micro-fertilizer sprayed should vary depending on the growth conditions. Generally, 40-75 kg of fertilizing liquid can make the stems and leaves of vegetables wet.
The number of times is off. Foliar application generally uses less fertilizer, so it is difficult to meet the needs of all growth and development processes at one time. Therefore, it is generally appropriate to spray 2 to 4 times according to the length of the vegetable growth period.
Time is off. In order to reduce the loss of micro-fertilizer during the spraying process, it is beneficial to absorb the leaves. It should be sprayed in the afternoon or to the evening when it is cloudy or sunny. This can be used to increase the residence time of the fertilizer solution on the vegetable leaves. Apply the effect.
Mixed spray off. Mixing and spraying with micro-fertilizer, or mixing with other fertilizers and pesticides, can save the process and play the role of “one spray and multiple effects”. However, when mixing, pay attention to clearing the fatness and medicinal properties. If the properties are opposite, they are mutually obstructive and must not be mixed. All kinds of micro-fertilizers should not be mixed with alkaline fertilizers such as grass ash and lime; zinc fertilizer should not be mixed with superphosphate; copper fertilizer should not be mixed with potassium dihydrogen phosphate solution. When mixing with pesticides, the dual effects of fertilizer efficiency and efficacy should be considered. For the sake of prudence, a small amount of solution of micro-fertilizer and pesticide should be placed in the same container before mixing. If there is no turbidity, precipitation and bubbles, it can be mixed. If any of the above phenomena occur, Indicates that the two cannot be mixed. Generally speaking, all kinds of micro-fertilizers cannot be mixed with alkaline pesticides. When preparing a mixed spraying solution, generally, a micro-fertilizer is first formulated into an aqueous solution, and then other medicines and fertilizers are directly added to the prepared micro-fertilizer solution for dissolution.

Sanding Belt

Abrasive belt is a belt-shaped tool that can be ground and polished, which is made by bonding abrasives to flexible materials such as paper and cloth with a binder. It is a main form of coated abrasives. Its basic composition is: base material, abrasive and binder, collectively called the three elements of abrasive belt. Abrasive belt is the main tool of the sanding process. Abrasive belt grinding is a soft grinding method, which is a compound processing abrasive tool with multiple functions of grinding, grinding and polishing.

Abrasive tools are tools for grinding, grinding and polishing. Most of the abrasives are artificial abrasives made of abrasives and bonding agents, and natural abrasives are also directly processed from natural ore. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in the processing of non-metallic materials such as food processing, paper industry and ceramics, glass, stone, plastic, rubber, and wood.

Abrasives are divided into natural abrasives and artificial abrasives. All materials that can be used for grinding or grinding in nature are collectively referred to as natural abrasives.

Natural abrasives mainly include: natural corundum and garnet

Artificial abrasives mainly include: white corundum, brown corundum, silicon carbide, zirconium corundum, synthetic diamond, cubic boron nitride.

How to choose a suitable abrasive belt and further improve the smoothness and flatness of sanding is a very important issue in the use of abrasive belts. Due to the differences in the three major components of abrasive belts and various characteristic factors, abrasive belts can be divided into many varieties according to different grinding objects, grinding conditions and grinding requirements. The following is the classification of abrasive belts according to abrasives. Different abrasive belts are suitable for different products. The following types of belt operations are: automatic grinding, mechanical hand grinding, desktop grinding, and manual tool grinding.

Types of abrasive belts (according to abrasives):

1: Accumulated abrasive belt

Application: Widely used in polishing various non-alloy, low-alloy and high-alloy steel, stainless steel, brass, bronze and other non-ferrous metals. Good self-sharpening, long service life, uniform grinding volume and uniform surface roughness.

2. Brown corundum belt

Application: Widely used in metallurgy, machinery, shipbuilding, wood, building materials, textile printing and dyeing industries. Grinding and polishing of bamboo and wood products, decorative panels, stainless steel, non-ferrous metals and other complex surfaces. Fast cutting, heat resistance, long service life, efficient wear resistance.

3. Ceramic abrasive belt

Application: Widely used in grinding chromium steel, chromium-nickel steel, stainless steel, high-alloy steel, nickel-based alloy, titanium alloy, brass and bronze, etc., with good self-sharpening, strong grinding, and large removal of grinding materials.

4. Silicon carbide belt

Application: Widely used in the grinding and polishing of brass, bronze, titanium alloy, aluminum alloy, glass, ceramics, minerals, stone, rubber, and synthetic materials. The sand surface is sharp, with very high strength and grinding ability, suitable for grinding medium and high density plates. The bucky has strong tension and ultra-wide sub-tension, which can be used for ultra-large abrasive belts.

5. Zirconium corundum abrasive belt

Application: Widely used in the grinding and polishing of steel, alloy steel, cast iron and non-ferrous metals, medium load or heavy load powerful grinding. The rigid polyester fabric is resistant to strong tension and impact, has high abrasion resistance, and has excellent comprehensive cost performance.
