What is the best month to plant spring corn in Shandong? When is the best time to plant?

Spring corn planting time in Shandong

Because the planting time of spring corn is relatively early and the growth and development stage is longer, resulting in a higher yield of spring corn, Shandong area starts planting spring corn in early April and harvests it at the end of August. Corn seeds usually germinate at 6-7 degrees, but the germination process is extremely long. If the planting time is too early, the temperature changes drastically, the seeds are easily damaged by frost, and the germination rate is reduced.

Spring corn planting method

1. Choose good varieties. Choose spring corn with strong root growth ability and remove small grain disease. Then expose it to the sun for 3 days, which can effectively improve the water absorption capacity of the seeds.

2. Mechanical sowing: Choose mechanical sowing, control the number of sowings, and ensure that the sowing amount per mu is about 4 pounds. When sowing, be careful not to let the seeds and fertilizer touch each other. The fertilizer should penetrate into the bottom layer of the soil and be placed about 5 cm below the seeds to avoid root burn.

Points to note when planting spring corn

1. Weeding: Correctly select the dosage form and concentration of the herbicide, and clearly understand the period and method of use to avoid pesticide damage. Thin out and determine the seedlings in time after emergence.

2. Density: Reasonably increasing the planting density is an important measure to increase the yield of spring corn in Shandong. The appropriate planting density should be determined based on the characteristics of the variety and the local environment, soil fertility and management level.
