灌溉条件下混播、间播牧草的潜在生产力

Potential productions of Mixture Sowing and Spacing Sowing Grasses Under Irrigation Conditions.

本文通过对混、间播牧草进行三因素、三水平的正交试验研究,提出了灌溉条件下混播、间播牧草高产的最优组合模式,从经济角度探讨了灌溉水源有限条件下混播、间播牧草的经济灌溉定额和关键灌水期,并对混、间播牧草潜在生产力进行了综合评价.

Through three—factor and three—level orthogonal experiments for the mixture sowing and spacing sowing grasses this article puts forward optimum combination patterns of mixture sowing and spacing sowing grasses under irrigation conditions. From the point of view of economy, it details the economic irrigation quotas and the key irrigation periods of mixture sowing and spacing sowing grasses under the condition of limited irrigation water. In the sense of establishing an artificial fodder base and an agriculture technique, it conducts a synthetic appraisal on potential productions of mixture sowing and spacing sowing grasses.
