Detailed Explanation of Corn Planting Methods and Technical Key Points
Many people enjoy eating tender corn and often make boiled tender corn their first choice for breakfast. Corn is grown over a very wide area in China and is one of the indispensable crops planted every year in the north. It is very suitable for both individual planting and large-scale planting. Today, Qinong Net brings you the corn planting methods!
1. Land Selection and Preparation
The first thing is spring plowing. After Qingming, spring plowing begins. It is best to choose after rain, as this can ensure the soil stays moist. The purpose of plowing is to loosen the soil and retain moisture, so that corn has sufficient water during rooting, sprouting, and subsequent growth, ensuring good corn growth. On the plowed land, dig pits in aligned rows to prepare for the next step of sowing.
2. Seed Selection and Sowing
When selecting corn seeds, choose seeds with intact kernels, plump and full, and free from pests and diseases. Keep the temperature at about 11 degrees at 5 cm above the ground. The spacing should not be too small. For a 50 m row, plant about 150 plants, with each plant spaced about 30 cm apart. Put 3-4 seeds in each pit. After sowing, press the soil down, with a thickness of about 4 cm.
3. Fertilizing and Weeding
Corn fertilization is somewhat different from that of other grains. After spring plowing, farmyard manure needs to be applied to the land. Mix the manure and chemical fertilizer evenly and spread it on the land. When the corn seedlings grow to knee height, fertilize again. During the tasseling stage, mix 0.5 jin of potassium dihydrogen phosphate and 1 jin of urea with 100 jin of water for foliar spraying. Starting from when the corn seedlings sprout, remove the weeds around the corn seedlings. Weeding is needed once at each stage.
4. Pest Prevention and Control
Pests are the most hated creatures for every grain crop. Generally, at every stage the corn seedlings go through, such as sprouting and the seedling stage, pesticides need to be sprayed to remove pests. For example, for white grubs, use phoxim emulsifiable concentrate to drip evenly along the corn roots. You can also use dichlorvos per mu mixed with sandy soil and scatter it evenly along the corn seedlings in the morning. Generally speaking, as long as you pay attention to maintenance during each period of corn growth, it will be fine.
The above are the corn planting methods. Corn should only be harvested after the kernels mature. Also, pay attention to observing the nutritional status and fertilize in time. There are especially many pests that like corn, so be sure to guard against pests. If you want to learn about corn pests and control methods, please continue to follow Qinong Net.
