Orchard cover has obvious ecological advantages and yield increase effects. Its main advantages are as follows:
The first is to be able to protect the land: Before the new leaves of the orchard are unleashed, or the young orchard orchards, the land between the fruit trees is often exposed and the amount of evaporation is large. During the rainy season, rainwater is also easily lost. After intercropping, it can not only reduce the loss of rainwater, but also reduce the amount of evaporation, make the water holding capacity of the soil relatively stable, and enhance drought resistance.
The second is to preserve fertilizer: After covering grass, it can reduce the volatilization of fertilizers and the loss of rainfall, and increase the utilization of fertilizers.
The third is to improve the soil: after grass rot, soil humus can be increased and soil aggregate structure can be improved. Covering grass for 3 to 4 years can increase soil organic matter by 0.4%----0.5% and prevent soil compaction. Loose topsoil.
The fourth is to be able to adjust the temperature: Long winter season, Gaizhi can increase soil temperature by about 2 degrees, and enhance anti-freeze capability. In the summer season, grass cover can reduce the soil temperature by about 10 degrees.
The fifth is the ability to eliminate grass: uncovered orchards, in the weeds sprout season, generally there are more than 100 weeds per square meter, orchard orchards, generally do not sprout or rarely weed.
Sixth, it is able to fight disasters: one can reduce the occurrence of red spider pests, and secondly, it can prevent the lodging of fruit trees. Third, it can reduce the rate of flower and young fruit loss.
Seventh, it can increase production: General Gaiguo Orchard can increase yield by more than 5%, and more can increase output by 10%.
The eighth is to improve the quality: as long as it persists for a few years to cover the grass, after improving the soil, the fruit has a good appearance and gloss, and the sweetness is correspondingly improved. In the technical operation of grass cover in orchards, the following points should be mastered:
First, the grass cover time can cover the grass all year round, but the coverage effect is better before the low temperature or high temperature comes.
Second, cover grass species straw, wheat straw, rapeseed and legume straw, lake grass, fresh grass, etc. can all be covered, and localities can be based on local grass resources.
Third, the amount of grass cover is generally 1 acre cover about 1,000 kg of hay, fresh grass to 2500 kg is appropriate. There should be more young orchard and the orchard can be reduced.
