Production practice shows that intercropped mung bean technology in cotton field is an effective production technology that implements multi-cropping of cotton fields and improves the economic benefits of cotton fields, and is welcomed by cotton farmers. The cotton seedling mung bean now introduce the following key technologies for cotton farmers reference. First, the specifications of sowing. Cotton interplanted mung bean mainly cotton, green beans piggyback, so mung bean in the field there is a group of moderate problems. Practice shows that over the past few years, the size of the line to plant cotton, Dahon 90cm, small 40cm, intercropped mung bean in a large line, acres stay 3000-5000 appropriate, sowing time in order to sow mung beans before sowing cotton is appropriate, General mung beans 3-5 days earlier than cotton, so as to shorten the symbiotic period. Second, the selection of early maturity and high yield mung bean varieties. There are two varieties currently planted more. First, Yang green beans, the masses said "fire green
