Wisdom. Characteristics of Hui 3000 Corn Seeds

Characteristics of maize variety Zhihui 3000;

1. Topping ability: This variety has strong topping ability, and the whole seedling can only be caught after sowing, so it is unnecessary to check and replenish the seedling, especially in the case of poor soil preparation quality and less labor.

2. Fertilizer tolerance: the soil in mountainous areas or hillsides is barren, with low organic matter content and low fertilizer input, which requires high yield and barren tolerance.

3. Drought and waterlogging tolerance: Spring drought, summer waterlogging and autumn drought are common phenomena, which often lead to the decline of corn yield, requiring varieties to be drought and waterlogging tolerant.

4. Disease resistance: Head smut is a quarantine disease in Northeast China. Bacterial blight and bacterial wilt are quarantine diseases in Huang Zhun sea area. Gray leaf spot is a quarantine disease in southwest China. Diseases such as leaf blight and rough dwarf disease also occur from time to time in Shanxi, causing immeasurable losses to farmers. In recent two years, the price of corn has fallen, and it is difficult for growers to sell grain. The quality of corn has attracted more and more attention. Ear rot has become a fatal weakness that hinders quality, and varieties are required to resist ear rot.

5. Low temperature tolerance: Late frost retreats in Northeast China, Datong, Shanxi, Northwest Gansu, Xinjiang and other places, and often encounters late spring cold. For example, from April 26th to May 20th, 2004 1 day, there was a large-scale cooling in northwest China, especially in Wuwei, which caused a large-scale freezing injury to maize seedlings. On May 2, 20 16, some areas in Zhangye, Gansu suffered from low temperature, and some varieties were frozen, resulting in lack of seedlings and broken ridges, which greatly affected the yield. Therefore, it is required that varieties can tolerate low temperature at seedling stage.

6. High temperature resistance: In the northwest and northeast spring corn areas and the Huanghuaihai summer sowing areas, corn often encounters high temperature during flowering and pollination, which affects the seed setting rate and leads to a decline in yield, requiring varieties to be resistant to high temperature.

7. Lodging resistance: Mechanical harvesting has become a trend, especially with the follow-up of grain mechanical harvesting, which requires that the lodging resistance of varieties must pass.

8. Good maturity: In the mountainous areas of Northeast China, Northwest China and Shanxi, the first frost in autumn comes early, and immature plants often encounter the first frost, so it is required that the maturity is appropriate.

9. Fast dehydration: With the land circulation and the expansion of planting scale, the difficulty of grain drying will become an obstacle affecting the quality of corn. Of course, it can solve the problem of ear drying, but the cost is relatively increased, which requires rapid dehydration of ear. In this sense, mature varieties with live stalks will have less and less space.

10, stable yield: the annual output should be relatively stable, otherwise growers can't choose varieties.

1 1, simple operation: the decrease and aging of rural labor force require simple cultivation techniques and easy operation. Land circulation and large-scale planting also need simple operations.
