(2) when summer maize seedlings grow to 3-5 leaves, namely 6 months and 20 days, the special herbicide for the maize is sprayed with the nicosulfuron atrazine by a machine to prevent and control field weeds and wheat seedlings;
(3) mechanically sowing soybean seeds in 22 days in 6 months, wherein the row spacing is 30cm, the plant spacing is 15cm, and watering is carried out in time after sowing according to the soil moisture content.
Further, the summer corn soybean intercropping mode is as follows: and (2) interplanting of 2 rows of corns and 6 rows of soybeans, wherein the row spacing of the corns is 60cm, the plant spacing of the corns is 10cm, the row spacing of the soybeans is 30cm, the plant spacing of the soybeans is 15cm, the distance between the soybeans and the corns is 50cm, the width of each of the 2 rows of corns and the 6 rows of soybeans is 1, and the width of each of the 2 rows of corns and the 6 rows of soybeans is 3.1 meters.
Further, after the corn is sowed in the step (1), head covering water is irrigated in time according to the soil moisture content, and one-time sowing of full seedlings is guaranteed.
Further, the dosage of the special herbicide for corn in the step (2) is 100mL per mu.
The invention has the following advantages and positive effects: utilize the space-time difference of maize soybean to carry out chemical weeding, can avoid the influence of Huang Huai Hai summer sowing district high temperature to the soybean, prolong maize harvesting period, improve maize soybean output, can effectively weed again and the wheat seedling to can not produce the phytotoxicity to soybean maize, avoid the output loss of soybean maize, practice thrift the weeding cost.
