Different soil textures, suitable for the application of farmyard fertilizers are also different. Chicken manure, cattle and sheep manure, pig manure and other farm manure have their own characteristics, suitable for different soils.
The loam texture is the best. All manures are suitable for application. The clay texture is heavy. In order to improve soil quality, it is advisable to use high concentrations of organic matter and relatively low nutrient content of feces and sheep manure and pig manure; sandy soil leakage leakage serious, nutrients The loss is fast and it is also suitable for the application of cattle and sheep feces and pig manure with high organic matter content and relatively low nutrient content.
The organic matter content of chicken and duck dung is about 25%, and the nutrient content is relatively high. It is currently applied more farmyard manure. Chicken manure is a hot manure, producing more heat during fermentation. It is better for soils with deeper soil and lower soil salt ion concentration. However, chicken and duck dung can easily induce underground pests, and uric acid and nitrogen can not be directly absorbed and utilized by crops and must be fully decomposed before application. Chicken and duck manure after full maturity as base fertilizer and top dressing can be.
The content of organic matter in sheep manure is about 20%, the nutrient content is moderate, and a small amount of nitrogen fertilizer can be added when it is decomposed. Sheep manure has a good effect, good effect that year, suitable for application to all kinds of soil and various crops. After the sheep manure is fully cooked, it can be used as base fertilizer and top dressing. Cow manure is slow to ripen, fertilizer effect is slow, fermentation temperature is low, and it is a cold fertilizer. To speed up decomposition, fresh cow dung can be sun dried and mixed with other manure. Cow dung has low nutrient content and a large carbon-nitrogen ratio. Pay attention to the application of quick-acting nitrogen fertilizers during application to prevent the microorganisms from competing with crops for nitrogen decomposition. The fully decomposed cow dung is generally only used as base fertilizer, and the effect of improving soil quality is better.
Pig manure is rich in nutrients, potassium content is highest in farmyard manure, nitrogen and phosphorus content is second only to sheep manure. The texture of pig manure is finer, ammoniated bacteria are more, it is easy to decompose, the fertilizer effect is fast, which is conducive to the formation of humus, and the effect of improving soil quality is good. The pig manure is soft and has strong stamina. It is a warm fertilizer and is suitable for all kinds of soil and various crops. After fully decomposed pig manure can be used as base fertilizer, top dressing.
A blunt cannula is a small tube with an unsharp rounded end, specifically designed for atraumatic intradermal injections of fluids, for example injectable fillers. It has ports on the side allowing the product to be dispensed more evenly. Over the years a wide array of blunt-tip micro-cannulae have been designed that offer variety in flexibility, size and diameter, but all are very small in diameter. The modern micro-cannulae allow both superficial and more involved procedures. Different sizes can also be used to inject fillers of nearly any type of level of viscosity. Extremely flexible, long micro-cannulae can be used to employ the "fanning technique", a method that allows for treatment of a large area through a single puncture point.
