在山地栗园中实行板栗、紫穗槐与农作物的立体化间作栽培,改善了栗园小气候及土壤营养条件;既促进了板栗的生长结实,又增加了间作物的收入,使单产效益相当于同等条件下板栗单作的2.55倍或粮食单作的4.96倍,产投比达到5.04∶1。该模式现已在当地推广22.73万亩。 Chestnut, Amorpha fruticosa and crop three-dimensional intercropping cultivation were implemented in the mountain chestnut garden to improve the chestnut microclimate and soil nutrient conditions; not only promote the growth and fruiting of chestnut, but also increase the income of the intercrop crops so that the yield per unit area is equivalent to Under the same conditions, the chestnut single 2.55 times or 4.96 times the grain for single, production to investment ratio reached 5.04: 1. The model is now promoting 22.73 million mu in the area.
