As we all know, in rural areas, it is mainly planting. In many places, they grow a series of crops such as rice, wheat, corn or sorghum to earn income. However, in order to increase rural income, it is necessary to increase output and realize various benefits. Therefore, in order to improve the planting efficiency of corn, we can start with planting selection or selecting suitable planting methods and planting areas. Of course, it is necessary to choose new varieties or seeds that adapt to the local environment and geological conditions and interplant them, such as corn interplanting potatoes, or some crops that don't need much sunshine, so as to achieve double benefits.

In order to achieve high yield of corn, we must first choose good varieties. If this variety has no high yield potential, no matter how well it is managed, it is impossible to achieve high yield.

Corn varieties should generally choose high-yield varieties with moderate growth cycle, disease resistance, lodging resistance and strong adaptability. Generally speaking, good varieties will be recommended before sowing date. When selecting corn seeds, special attention should be paid to corn seeds with complete seeds, uniform size, high seed vitality and high purity. Full and uniform particles can ensure the orderly emergence of corn seedlings; High energy ensures high germination rate and sufficient nutrients. Therefore, a good variety must also have high-quality seeds.

The degree of close planting will directly determine the yield and quality of corn, and close planting of corn is affected by many factors, including soil fertility and local climate conditions. According to past experience, in grain planting, except wheat, the planting density of other crops represented by corn is relatively low. Therefore, by moderately increasing the planting density of corn, the yield per unit area can be increased. According to the calculation, in the planting areas where the corn yield is above 500 kg/mu, there are 4500~6000 compact corn plants/mu and 3500~4000 non-compact corn plants/mu.

The best harvest time is when the female ear spins silk but is not pollinated. After that, new shoots are harvested every 1-2 days, and the end of 7- 10 days.

The method of picking bamboo shoots is to grasp the bract leaves of flag leaves or panicles with one hand, and use a little force on the side (perpendicular to the extension direction of leaves) to pick complete bamboo shoots to avoid cutting off the leaves, so as not to affect the growth of plants and the growth and development of the next panicle.
