| 释义 | crop rotation noun[ U ] uk /ˈkrɒp rəʊˌteɪ.ʃən/ us /ˈkrɑːp roʊˌteɪ.ʃən/ a method of farming where a number of different plants are grown one after the other on a field so that the soil stays healthy and fertile (= able to produce crops)庄稼轮作 Farming - general words agricultural extension agroecology agroforestry biodynamic cultivate emergence homestead hungry gap hydroponic hydroponically inorganically landrace reap the Agrarian Revolution thrash tillage U-pick unharvested unsown untillable Crop rotation kept soil nutrients high and avoided over-farming. The old forms of crop rotation with fallow periods were often displaced by legume-rotation field-grass agriculture. Examples of crop rotationcrop rotation These practices may include cover crops, manures, compost, croprotation, intercropping, and biological pest control. Furthermore, croprotation, and particularly no-till, promote diverse invertebrate populations, which play an important role in maintaining nutrient cycling and soil structure. On the other hand, organic production techniques, particularly croprotation, can reduce risk in the longer term. Soil samples were collected from the same plots for the duration of one croprotation cycle. But obtaining a certificate required not only that one adopt techniques such as croprotation, manuring and the building of field contours. Therefore, once a candidate crop is identified, it may be many years before the crop is ready to be included in a croprotation. The added fertilizer to the croprotation is adjusted to allow spring barley to receive fertilizer too. Commercial oats are often contaminated with wheat due to croprotation, although oats prolamins are less toxic. The two alternatives include continuous soybean and a croprotation that includes winter wheat and soybean. This study indicated that croprotation and reduced tillage have a number of positive effects on the ecological sustainability of agroecosystems. Farmers will select crops based on the return they get from each crop and other constraints, such as croprotation, labor, or machine availability. The sustainability and productivity of the prevailing rotation are being compared with the sustainability and productivity of an improved high input and intensive croprotation. Subsequent trials were planted on a different patch of land following a pre-set croprotation plan for each location. As a result, a farmer who chooses to implement a long-term diversified croprotation or other conservation practice assumes all the risks. Effect of croprotation and fertilization on maize and wheat yields and yield stability in a long term experiment.
