本文通过每年应用杂草、玉米秸杆、紫花苜蓿覆盖、翻压旱薄山地枣园,试验研究了不同覆草类型对土壤水分、有机质含量、一等果率和产量的影响。其结果表明,不同覆草类型地面覆盖、翻压旱薄山地枣园,均有逐年增产的趋势。一等果率增加了23.3%,产量增加了64.2%,产值增加在97%以上,效益显著。其中覆盖材料以紫花苜蓿优于杂草,杂草优于玉米秸秆,因杂草成本低,取材容易,是最佳覆盖材料。
In this paper, weeds were covered with weeds, corn stalks and alfalfa and jujube fields in upland and hilly areas were drenched each year to study the effects of different grass types on soil moisture, organic matter content, first-rate fruit yield and yield. The results show that different types of grass cover the ground cover, turn over dry and drought mountain jujube, have a tendency of increasing production year by year. First-rate fruit rate increased by 23.3%, output increased by 64.2%, output value increased by more than 97%, with significant benefits. Among them, alfalfa is better than weed in covering material and weed is better than corn stalk. It is the best covering material due to its low cost and easy drawing.
