我们对玉米生育的全过程进行了认真、反复的观察,初步认为,管好玉米必须做到“保苗、保穗、控中间”,总结出“三叶间(苗)、五叶定(苗)、六至九叶控、十叶往后肥水攻”的管理经验。保苗玉米出苗后,管理的中心是保证全苗、匀苗、齐苗、壮苗。玉米是一种单株生产力很高的作物,缺一株就少收几两粮食,因此必须做好查苗补苗的工作。补苗的方法,一是育苗移栽,二是直接补籽。据调查,移栽补苗的每穗656粒,每斤1,900粒,补籽的每穗406粒,每斤2,300粒。所以补苗以移栽补苗
We have carried out serious and repeated observations on the whole process of maize growth. It is initially believed that the management of maize must be “seedling-keeping, spike-earning and control of the middle” and summed up the “three-leaf clover (seedling) , Six to nine leaf control, ten leaves after the fertilizer attack ”management experience. Seedling seedlings after emergence, the management center is to ensure that the whole seedlings, uniform seedlings, Qi Miao, strong seedlings. Corn is a plant with high productivity per plant. If one plant receives less than two grains of food, it must do a good job of looking up the seedling and replanting seedlings. Fill seedling methods, one transplanting seedlings, and second, direct seeding. According to the survey, transplanting seedlings of 656 spikes per ear, 1,900 pounds per catty, seeded seeds per ear, 406, 2,300 catties per catty. So fill Miao to transplant seedlings
