Planting methods and matters needing attention of Maize

The season has come again, and many people have already begun to plant corn. There are more and more varieties of corn, it is dazzling to see. There are strawberry corn, sweet corn, colored corn, purple corn, glutinous rice corn, black corn, starch corn specially for pigs, and so on. But my favorite food is sweet corn and glutinous rice corn.

Strawberry corn

Corn planting, first land preparation and ploughing, large ridges to select appropriate ploughing, stubble Harrow fine middle and upper fertility plots, flat and depression land is not limited. In the ridge distance of 0.5 meters on the basis of the original ridge, that is, the combination of two ridges into a row spacing of 1 meter ridge, ridge width of about 0.7 meters is more suitable.

The growing period of corn is short and warm and rainy is required during the growing period. Therefore, large-scale planting usually begins in March. It is recommended to soak the seeds in warm water before sowing. Soak corn seeds in 2 portions of boiling water and 1 part of cold water at about 55 degrees Celsius for 12 hours, then sow them in the sun. This method can not only accelerate the process of seed water absorption, but also kill the spores of powdery mildew attached to the seed surface.

Colorful corn

Generally speaking, there are two main sowing methods of corn: strip sowing and on-demand sowing. According to the planned row spacing, plant spacing, fertilizing, planting and covering soil, this method is often used in interplanting corn. Strip sowing is mechanical sowing, which has high working efficiency and is suitable for large area planting. Sowing depth: in general, the sowing depth is 3-5cm, sometimes it is appropriate to increase the sowing depth depending on the situation.

Sweet corn

The growth period of maize is generally: seedling stage, three-leaf stage, jointing stage, big trumpet stage, heading stage, flowering stage (silking stage), filling stage, milk ripening stage, wax ripening stage and full ripening stage. Maize consumes a lot of water. Maize seedling stage refers to the period from sowing to jointing, which is a vegetative growth stage dominated by rooting and differentiation of stems and leaves. The growth characteristics of this stage are as follows: the root system develops rapidly, but the growth of aboveground stems and leaves is relatively slow. For this reason, the central task of field management is to promote root development and cultivate strong seedlings, so as to meet the requirements of "four seedlings" of early seedling, sufficient seedling, full seedling and strong seedling.

Glutinous rice corn

The ear of corn can be divided into female ear and male ear, and the male ear (male flower) at the top is also smallpox. The one with beard (filament) on the stem is the female ear, and the filament is the female flower of corn. Generally speaking, the corn ear refers to the female ear, that is, the corn cob corn ear generally grows with the corn whisker, when there is a beard, it is necessary to pay attention to pollination. Pollination directly affects the quality of the stick, whether it can grow up or not depends on it, so this is a very important link. It is worth noting that in the later stage, we must pay attention to corn ear rot, pest control, field management, and pay attention to branch ventilation.

Focus on agriculture, rural areas and farmers, pay attention to rural areas.
