Covering orchards in orchards can create a good environmental condition for the roots of the fruit trees and even the entire tree body for growth and development. It is a technical measure that can not be ignored to improve the quality of fruit and achieve stable and high yields in dry orchards.
Mulching improved the physical and chemical properties of the soil. Covered orchards have changed groundwater, gas, and thermal environments. Soil temperature changes are relatively stable. It has been determined that the soil moisture content in a 20 cm layer of grass in a grass-covered orchard is 4.3% -8% higher than that in a clear-cultivated orchard without grass, and the soil organic matter content is increased by 20-30% . Covering grass promotes the growth and development of the tree. The increase of soil humidity and the large amount of earthworm activity make the soil loose, increase the absorption of roots in the shallow soil layer, and develop the root system of the fruit tree. It promotes flower bud differentiation, neat flowering in spring, large and thick petals, and strong color. The diameter of the canopy is increased by 5% -10% compared to the clear farmland, and the yield is increased by about 20% compared with the clear farmland. Reduced diseases, insect pests, and improved fruit quality. Orchard mulching can reduce water transpiration, inhibit weed growth, control soil erosion, reduce orchard pests and diseases, increase bagging fruit coloring and reduce cracks, and ensure high-quality and fruitful fruit trees.

Water Test Strips 15 Parameters
Detection method:
visual
Operation method:
1. Visual inspection: Immerse the test area of the test paper into the fully stirred fresh drinking water, and take it out immediately;
2. Put the edge of the strip against the edge of the container to remove excess water samples;
3. Compare the test strip with the colorimetric table on the bottle label, and record the test result in the determination time: 0 ~ 60 seconds. Use visual.
Storage conditions:
The test paper should be stored in room temperature, dry environment, away from a variety of chemical reagent environment, avoid direct sunlight. This product does not need to be refrigerated (if it is stored for a long time, it should be restored to room temperature and opened for use).
