怎样确定作物的目标产量作物的目标产量即是计划产量。目标产量应根据土壤肥力来确定，因为土壤肥力是决定产量高低的基础。目标产量的确定是配方施肥技术的前提，定得过高过低都会失去配方施肥的意义。一般地说，目标产量通常用经验公式来表达。先做田间试验，用不施任何...
How to Determine the Target Crop Yield The target crop yield is planned. The target production should be based on soil fertility, as soil fertility is the basis for determining the level of production. The determination of the target yield is the premise of the formula fertilizer technology, set too high too low will lose the significance of formula fertilization. In general, the target output is usually expressed by empirical formula. Field trials first, do not impose any ...
