谷子耐旱、抗逆性强、适应性广,在我国栽培历史悠久,是典型的半干旱型作物,丘陵山区种植较多。河北省太行山区是谷子的主产区之一,过去由于种植方式传统,山区谷子单产较低,农民种植谷子只是为了自需。为了提高谷子的单产,在谷子种植前覆盖地膜,以达到蓄水保水、增温提墒的目的,再加上张杂谷杂交种增产效应,大大提高了谷子产量。现将杂交谷子地膜覆盖栽培技术介绍如下。
Millet drought, strong resistance, wide adaptability, cultivation in our country has a long history, is a typical semi-arid crop planting more hills and mountains. Taihang Mountain in Hebei Province is one of the main producing areas for millet. In the past, due to the traditional planting methods, the yields of millet in the mountainous areas were lower and the farmers planted millet only for their own needs. In order to improve the yield of millet, mulching before mulching plastic film in order to achieve the purpose of water storage and water retention, warming soil moisture, coupled with Zhang Zhagu hybrid yield, greatly increased the yield of millet. Now hybrid millet mulching cultivation techniques are as follows.
