我国南方的花生,大都种在丘陵的红黄壤旱地和高山坡地上。前者土质较为粘重、后者瘠薄,不利于花生插针结果。而且南方上半年气温由低逐渐升高,6—8月正值花生开花和插针结果时期,常遇高温干旱,对子房柄膨大结实极为不利。如果加上栽培管理不良,花生结实率就更低。笔者在本所红壤旱地上,对中籽芙蓉花生进行了五年的连续试验观察,其结果:亩产111.25—210.65公斤,五年平均156.4公
Most of the peanuts in southern China are planted in the hilly red and yellow soil of dry land and high mountain slopes. The former soil is more sticky soil, the latter barren, not conducive to peanut pin results. In the first half of the year, the temperature gradually increased from low to high in the south. During the period from June to August, peanut flowering and pinpointing occurred, and it often encountered high temperature and drought. It was extremely unfavorable to the enlargement and fruiting of the ovary. If coupled with poor cultivation and management, peanut seed rate is lower. The author of this red soil arid land, the seeds of hibiscus peanut for five years of continuous experimental observation, the results: per mu 111.25-210.65 kg, five-year average of 156.4 kilometers
