Maize two-plant cultivation technology is the corn cultivation technology for leaving two plants per hole after the seedlings are planted. The main advantages of this cultivation technology are: strong ventilation and light transmission, high planting density, and can achieve ton production (1000 kg per mu). The cultivation techniques mainly include the following points:
Variety selection should use dwarf and high product species, such as Zhengdan 958, Qinlong 11 and so on.
The cultivation methods are wide and narrow rows of cultivation, with a width of 80 cm, a narrow row of 40 cm, and two rows of planting; the distance between the points is 40 cm, double seedlings per hole, and 5000 plants per acre. Spring mulching is applied to cover the mulch, and the ground temperature can be increased by using the mulching.
Watering seedlings in a timely manner to timely irrigation of seedlings to ensure that all seedlings sowing seedlings, Miao Qi uniform; in case of drought, pouring enough water, pumping male water and Shengshui water.
Rational fertilization based on the application of base fertilizer before sowing, should focus on jointing period and large bell-mouth phase timely fertilizer. General Mushi organic fertilizer (basal fertilizer) about 1500 kilograms, compound fertilizer 25 to 30 kilograms per mu; 5 to 6 leaves period to pull out joint fertilizer, Mushi urea 20 kilograms; big bell mouth combined with cultivator soil, re-appropriate attacking fertilizer, Mushi 30 kg of urea.
Pest control focuses on prevention and control of armyworm and corn borer. The corn stickworm can be sprayed with 40% of water-containing phosphoramidite 500-600 times or 2.5% of the enemy-killed 1000-fold solution; the control of corn borer can be seen at the beginning of the corn leaves, and the young larvae can be clustered and left untreated. Before cutting into the stalk, 1.5% phoxim granules can be directly placed in the bell mouth; 90% of trichlorfon 800 to 1000 times can be used for the ear, or 75% of phoxim emulsion 1000 times Drop on the top of the ear, the effect is good.
