The so-called simple cultivation is to reduce redundant and inefficient labor and input, to make full use of the comprehensive effects of biology, to maximize the use of limited investment, to increase the ratio of production to investment, and ultimately to achieve low-cost and high-efficiency cultivation purposes.
1. Plant grass. A certain number of leguminous grasses were planted between the orchards and between rows. When they grow to a certain degree, grasses are cut in stages, sun dried and then buried under the canopy, and repeated year after year. If the growth is poor or the yield is reduced after several years, it should be replanted.
2. Cover grass. The cut grass, wheat straw, corn stalks, and poplar leaves, willow leaves, eucalyptus leaves, etc., are directly covered under fruit trees. Each tree is covered with grass and the projected area of ​​the tree crown is the standard. The thickness of the grass cover is 15-20 cm, and once coverage can be maintained for 2-3 years.
The above two management methods, especially those with poor soil moisture, poor ability to maintain water and fertilizer, and an orchard that is greatly affected by weather and temperature, are the ideal methods.
3. Intercropping. Intercropping on the ground, on the one hand, interplanting peanuts and soybeans in the summer and fertilizing the soil, accelerating the soil maturation, reducing the erosion of surface runoff, promoting the growth of fruit trees, and combining land use with land conservation; on the other hand, it will increase the income of orchards for the development of orchards. Provide funds to achieve long-term growth. However, high-stalked and strong-cropping corn, sorghum, pumpkin and other crops cannot be interplanted with it.
4. Use coal ash garbage fertilizer. It has been determined that coal ash has a moisture content of 39.02%, nitrogen 0.31%, potassium 0.70%, volatile solids 12.89%, and organic matter 22.22%. It also contains other nutrients and has long-lasting fertilizer effect, which can increase soil fertility, loosen the soil surface, and promote Roots of fruit trees grow and develop. If chemical fertilizers are mixed with coal ash, it can also reduce the leaching loss of chemical fertilizers, indirectly increase fertilizer efficiency, and increase the absorption capacity of the root system.
5. Orchard chicken. Chicken manure is a good quality fertilizer. An adult chicken can excrete 25 kilograms of chicken manure a year. If 50 or more chickens are cultivated per acre orchard, 1250 kilograms of high quality manure can be obtained in the whole year, equivalent to 80 kilograms of ammonium bicarbonate and 85 kilograms of superphosphate. 15 kg of potassium chloride and so on. Because chickens like to snatch small insects, they naturally act as "guardians" of fruit trees. They can promptly eat on the ground and fruit tree stem pests, such as adult beetles and larvae of beetles, small tigers, white ants, as well as the pests and eggs of these pests, thus greatly reducing orchard pests.
