1990～1997年,我们在东平县彭集镇后亭村进行杏树早期丰产栽培试验,探索杏树在沙滩地条件下早期丰产栽培技术。经过8年试验,取得了明显成效。 一、基本情况 试验园位于大清河南岸,原为沙丘,后改造整平;土壤有机质含量0.12％,N、P、K含量极低,漏肥漏水,雨季地下水位1.5～2.0m。试验园 From 1990 to 1997, we conducted an early apricot yield experiment in Houting Village, Pengji Town, Dongping County to explore early apricot cultivation techniques for apricot under sandy land conditions. After eight years of trial, has achieved remarkable results. First, the basic situation The test park is located in the south bank of the Qinghe River, was originally a sand dune, after the transformation of leveling; soil organic matter content of 0.12%, N, P, K content is very low, leaking leakage, rainy season groundwater table 1.5 ~ 2.0m.
