For high yields of spring corn, the sowing step is crucial
Improving the sowing quality of spring-sown corn and actively doing a good job in selecting and sowing good seed, fine land preparation, and timely sowing are crucial for ensuring a full stand and securing a bumper harvest of spring-sown corn. 1. Choose suitable varieties. Select suitable and appropriate improved varieties according to local conditions. According to heat resources and actual production conditions, mid-to-late maturing varieties with a growth period of 120-130 days should be selected...

Detailed Explanation of Key Techniques for Spring Corn Seedling Cultivation
The spring corn sowing period is approaching, and in production, seedling cultivation and transplanting should be done well to promote early and steady growth of corn and achieve high and stable yields. Fertilizing the seedbed: For transplanting with nutrient pot seedlings, prepare a seedbed 1.5 m wide and 20 m long for each mu of field, apply 250 kg of decomposed organic fertilizer, 2.5 kg of compound fertilizer, and...

Full Analysis of Key Points for Spring Corn Cultivation Techniques
Adapt to local conditions and select improved varieties. In plains and hilly areas, promote Yedan 13 and Xiyu 3, paired with Huayu 4, Zhongdan 32, Chenghai 1, and Yuanzheng 808; for interplanting in cotton fields, select the short-stalked, short-growth-period Yedan 22 and Yedan 51; in suburban areas, where fresh eating is the main purpose, waxy corn (2319, -21.00, -0.90%) such as Zhongnuo 1 can be planted....

Spring Corn Stubble Transplanting Soybean Cultivation Technique
I. Characteristics and Traits Soybean prefers warmth; seeds begin to germinate at 10-12°C, with 15-20°C being optimal; the optimal growth temperature is 20-25°C; the optimal temperature during flowering and pod-setting is 20-28°C. At low temperatures, pod-setting is delayed, and below 14°C flowering cannot occur; if the temperature is too high, the plant ends growth prematurely. Seed germination requires relatively more water; during the flowering period...

Spring planting fertilization tip: Effective potassium application boosts high yields in spring corn
Delayed senescence (staying green and late-maturing) refers to soybeans that, when they should be maturing, still have green branches and leaves with vigorous growth and seeds that are not yet plump, though not shriveled pods or shriveled seeds. The main cause of delayed senescence is excessive application of nitrogen fertilizer or application too late, causing excessive vegetative growth, delaying maturity, and affecting yield. To prevent delayed senescence in soybeans, it is necessary to timely...

Detailed Explanation of Key Points for Drought-Resistant Cultivation Techniques of Spring-Sown Corn
In recent years, as the area of spring-sown corn has increased, corn dwarf mosaic virus disease has also shown a worsening trend and has become a major disease of spring-sown corn. 1. Symptom identification: Corn dwarf mosaic virus disease can infect corn throughout the entire growth period, with damage being most severe at the seedling stage. Symptoms can appear as early as the three-leaf stage of corn, initially on...

A Complete Analysis of the Key Technical Points for Soil Testing and Formula Fertilization in Spring Corn
1. Choose suitable varieties. Select suitable and superior varieties according to local conditions; based on heat resources and actual production conditions, choose medium-to-late maturing varieties with a growth period of 120-130 days. Among spring corn varieties with relatively outstanding comprehensive traits, the main one is Nongda 108, etc. 2. Fine land preparation. Spring corn requires deep plowing, and the earlier the autumn plowing...

Key Technical Points for High-Ridge, Sparse-Planting, High-Yield Cultivation of Spring Corn
Many excellent spring corn varieties now require high ridges and sparse planting, but farmers generally adopt low ridges and dense planting, so the superior traits of corn cannot be fully expressed, seriously affecting farmers' income growth. This is especially true for excellent varieties such as Dongdan 60, Sanbei No. 6, Dongdan 13, and Zunyan No. 1, whose planting density per mu must not exceed 3000 plants, while...

Why Spring Corn Fertilization Should Be Light Early and Heavy Late
The corn borer, also known as the corn stalk borer. Spring corn is currently at the late whorl stage (funnel stage), and this period is the best time to control the corn borer. At the funnel stage, most newly hatched corn borer larvae crawl into the leaf whorl tube and feed on the mesophyll of the not yet unfolded leaves, and spraying at this stage makes it easy for the spray liquid to enter the leaf whorl tube, improving control effect...
