Abstract: Using the early ripening and low-strw type of the millet variety combined with the techniques of the cultural practices of closing planting and furrow seeding is one way to obtain 1,000 jin per mu for summer seeding millet. "Yang Tsung millet" is the representative variety of this kind. For past several years, we have carried out investigations on the biological characteristics and the cultural techniques of "Yang Tsung millet" and this has played a certain role in guiding agricultural production. "Yang Tsung millet" is originally a variety for spring seedling. Through many years of summer planting, the climatic conditions during the summer and autumn seasons have made "Yang Tsung millet" to possess some characters such as early maturing, dwarf straw, seedlings with reddish leaves, wide leaves, pointed earheads, short bristles, loose earheads etc. suitable for summer seedling. "Yang Tsung millet" has a short duration of vegetative growth and a long duration of reproductive growth. Its leaf is wide in the middle and attenuate toward both ends, it is suitable for close planting. The differentiation of the earhead commences 23 days after seed germination and completes within 14 days. The ratio of distribution of the dry matter in earheads and grains is great. The grain is of good quality. Practice proves that "Yang Tsung millet" is obviously an effective high-yield variety. "Yang Tsung millet" can reach the high-yield level of "1,000 jin of grain and 800 jin of hay" by means of high degree of close planting, furrow seeding together with cultural techniques of "three earlines" based upon its biological characteristics.
