Guozhai Wudai 103 acres of corn 1983 interplanting garlic, per mu corn 1000 kilos, more than 30,000 heads of garlic, garlic 300 pounds, the mu output value as high as 1,100 yuan. First, the reasons for the increase 1. Make full use of light and heat and land resources. Guojiazhai located in the Milky Way, soil fertility is higher, is a meadow soil loamy loam soil, containing 1.487% organic matter, total nitrogen 0.079%. Frost-free period of 140-160 days, a single type of corn can only use 80% of frost-free period. The main growing season of garlic In early spring and early summer, the main growing season of maize in summer and fall, garlic maize sets the main growth period of the two crops staggered, which played a role in time, space and ground force. Corn seedling need to squat seedlings, control of growth, it is garlic
