目前,郊区早稻和后季稻的每亩总穗数,一般可以达到40万穗以上,但由于穗头大小悬殊,以致产量相差二、三百斤。如八二大队,近年来有效穗数约在45~50万穗,每穗实粒数40~50粒,早稻亩产稳定在千斤以上,后季稻亩产900斤左右。而不少社队,虽然有效穗数也能达到45万穗,但每穗实粒数大都在35粒以下,影响到每亩的总实粒数。因此,防止小穗头,是提高单产,实现平衡
At present, the total number of spikes per mu of early and late rice in the suburbs can reach more than 400,000 spikes, but due to the disparity in the size of the spikes, the output varies by two or three hundred catties. For example, the Eighth Brigade, in recent years the effective number of spikes is about 45 to 500,000 spikes, the actual number of spikes per ear is 40 to 50 grains. The yield of early rice is stable above 1000kg, and the yield of late rice is about 900kg. Many communes and teams, although the effective spike can reach 45 million spike, but most of the grains per spike in grains below 35, affecting the total number of grains per acre. Therefore, to prevent small ears, is to raise yields, to achieve balance
