One defense
Do a good job of pest control. Since the crop stalk brought pathogens can easily spread through the soil (such as corn, leaf blight, head disease; wheat scab, etc.). Therefore, during the growth of crops, we must also pay attention to the prevention of pests and diseases to ensure the quality and yield of crops.
Two fill
1. Supplement Water The moisture content of the soil is good, and sufficient water is an important condition to ensure that the microorganisms break down the straw. The plot of orange stalks is returned to the field. In particular, there is a shortage of groundwater, and unwatered plots should be watered early to create a suitable environmental condition for microbial activity to facilitate straw decomposing.
2. Supplementary Nutrients The carbon-nitrogen ratio of common straw crops is approximately 80-100:1, whereas the carbon-nitrogen ratio required for soil microbial decomposition of organic matter is 25-30:1. If no nitrogen fertilizer is added, the microbial decomposition of straw is inevitable. It competes with crops for nitrogen and moisture in the soil and affects the normal growth of crops. Therefore, in addition to applying nutrients while returning cropland to the field, straw should be supplemented with ammonium bicarbonate in early spring when the soil is returned to the soil. If a certain amount of phosphate fertilizer is applied, the effect will be better.
Loose, but later water and fertilizer management must be appropriate, otherwise it may cause both greediness and premature aging, both of which will lead to reduced production.
Visual Testing is the most commonly used test method in industry. Because most test methods require that the operator look at the surface of the part being inspected, visual inspection is inherent in most of the other test methods. As the name implies, VT involves the visual observation of the surface of a test object to evaluate the presence of surface discontinuities. VT inspections may be by Direct Viewing, using line-of sight vision, or may be enhanced with the use of optical instruments such as magnifying glasses, mirrors, boroscopes, charge-coupled devices (CCDs) and computer-assisted viewing systems (Remote Viewing). Corrosion, misalignment of parts, physical damage and cracks are just some of the discontinuities that may be detected by visual examinations.
