How to increase corn yield

Fine sowing

quality improvement

Change the wheat to corn for the summer harvest. Change the intercropping corn in the middle and late May to the summer of June 5th-15th, after the wheat harvest, to ensure the quality of sowing. After the wheat is harvested, it can be cultivated in time, exterminated, and planted by machinery; or planted with a no-tillage sowing machine; or robbed of the summer direct seeding, leaving a height of no more than 40 cm. The use of equal spacing or size rows sowing, such as line spacing should generally be 50-65 cm; size row, the large row spacing should be 80-90 cm, small row spacing should be 30-40 cm. Sowing depth is 3-5 cm.

Reasonable dense planting

Guaranteed group uniformity

Establishing a reasonable group structure and ensuring the uniformity of the group is the key to creating high yields. Compact varieties have a large blade-to-blade and leaf-directional value and are suitable for dense planting. The current representative varieties include Zhengdan 958, Nongda 108, Ludan 981, and Liaoyu 18, etc.; flat type leaves are flat and have low leaf orientation, suitable for sparse planting. . Suitable planting densities in the Huang-Huai-Hai Plain area: flat-middle-middle-maturing hybrids, 3000-3800 plants/mu; compact medium-late-maturing hybrids and flat-panning mid-early-maturing hybrids, 4300-4800 plants/mu; compact mid-early hybrids , 4800-5300 strain/mu.

Scientific irrigation

Satisfy moisture supply

In case of drought during the ripening period of wheat, water should be made 3-7 days before the harvest, 30-40 cubic meters of water per acre or cast water after sowing. In the case of planting enough seeds, it is generally not necessary to water in front of the small bellmouth, and irrigation must be conducted in case of drought. After entering the big bell mouth period, you should not be short of water, and you should water according to the principle that the surface is wet and dry.

Timely late

Increase production by 10%

Lin Haitao particularly emphasized that in order to change the past practice of “turning the yellow leaves and hardening the grains, that is, harvesting,” it is “the dry leaves of the loquat, the appearance of the black layer, and the disappearance of the grain milk line, that is, the harvest of the grains when they ripen.” September 25 - October 1 harvest. Do not underestimate this small innovation, which can increase corn production by 5%-10%. The sowing of wheat is generally completed by October 10th. The timely receipt of corn does not affect the normal sowing of wheat, but it can achieve the purpose of harvesting wheat and corn in two quarters.

In addition, we must do the following.

Timely seedlings, Dingmiao. During the three-leaf period of maize, seedlings and five-leaf stage seedlings must not be delayed to prevent seedlings.

Go to pick up and pull out weak plants. For the varieties with adequate fertilizer and water conditions, which are prone to tillering, the tillers should be removed in time to facilitate the growth of the main stem. In the small bell mouth period, small and weak strains were removed in a timely manner to improve the uniformity of the population, ensure robust plants, and improve the ventilation and light transmission conditions of the population.

Detached. When tassels are removed without flowering, the tassels are removed by interlacing or septa, but they are not within 4 meters of the ground or the ground.

Rilled soil. In the seedling stage and the panicle stage, weeding and fertilization were applied twice in cultivating in time.

Disease prevention and pest control, reduce production factors. Seed dressing with seed coating to prevent disease at seedling stage; timely control of diseases such as rough dwarf disease, armyworm, thrips, corn borer, aphid, and ear worm, and rust and size spot disease.
