For more convenient reading, I share with you the information about agricultural technology, please click on my avatar to follow me. Corn is an indispensable crop in the world, the amount of use is large and extensive, although it is a food crop, less than 5% of it is directly eaten by people, most of the uses are for feed-type corn for livestock and poultry, as well as deep processing to make ethanol and other uses. Corn prices in these two years can be said to be very good, once straight to 1.4 ~ 1.5 yuan, planting corn, saving time and work, the level of efficiency depends on the yield of corn, how good, high-quality corn is naturally favored by the breeding industry, the higher the yield of the grower The higher the income. I believe that friends who grow corn are choosing good corn varieties for planting every year.
Corn diseases and insect pests, will affect the yield and quality of corn, let's first talk about the harm of corn drill heartworm, corn drill heartworm is also called corn borer, is an important pest affecting the high quality and high yield of corn, in corn occurs more commonly, corn leaves, stems, fruit ears, male ears and other parts will be harmful. Corn drill heartworm drill hole in the corn plant, affecting the nutrients upward transport, corn cob growth is not good, but also caused the corn resistance to lodging significantly reduced, once encountered a larger wind and rain, corn lodging yield reduction is not a star and a half. Corn drill heartworm harm corn cob, mostly in the corn female ear budding stage appears larvae, the larvae first eat the male ear of the bracts and male ears, with the increase in the age of the larvae, and then endanger the corn cob, corn grain, corn cob nodules and other places, resulting in nutrients can not be quickly transported to the corn grain storage, affecting the development of the fruit ear of corn, resulting in corn thousand grain weight decrease, increased hapsis grain, resulting in a great reduction in yield. Controlling corn drill heartworm has great benefits for improving the yield quality of corn.
After planting found that Yuqing 358 corn varieties, planted with other corn, the same management conditions, the occurrence of corn borer harm is much less, it is understood that this corn variety, but also china's independent research and development of the only non-GMO insect-resistant corn new varieties. The leaves of the Yuqing 358 corn variety have thicker villi on the surface, and the adult insects of the corn borer do not like to lay eggs on it, but prefer to choose the corn variety with less hair for spawning and reproduction, thereby reducing the harm of corn drill heartworms. Yuqing 358 is suitable for planting in the Huang-Huai-Hai region, the general plant height is 2.6 meters, the panicle position is 0.94 meters, Yuqing 358 is a shorter plant with a very strong ability to resist falling, there are developed root systems, more anti-fallen roots, the stems are thicker, and the stems with relatively high flexibility are enhanced, which enhances the ability to resist high winds, the root absorbs fertilizer and water, drought tolerance, these excellent conditions are the basis for corn to obtain high yields.
Yuqing 358 disease resistance performance, medium resistance to ear rot, gray spot disease, stem rot and so on. Planting in the Huang-Huai-Hai area is prone to infection with small spot disease, coarse shrinkage disease, southern rust, curvular leaf spot disease, powdery mildew and spike rot, which is the weakness of Yuqing 358, and it is necessary to prevent it in a targeted manner in order to obtain higher yields.
Yuqing 358 is suitable for planting in areas with an active accumulated temperature of more than 10 degrees above 2650. The source of the variety is y3011×y 06088, semi-compact plant type, suitable for dense planting, generally about 4000 to 4500 seedlings per mu, it takes about 102 days to emerge to maturity, in The Central Plains of Henan and other places, due to the high summer temperature, coupled with abundant rainwater, can be planted twice a year. In order to achieve high yields, it is also necessary to plant the variety in a place with fertile soil, good watering conditions, a long frost-free period and a higher temperature. Grain yellow, semi-purslane type, spring sowing average yield of 750 ~ 900 kg per mu, the highest mu yield of more than 1 ton, with a high yield potential, when introducing seeds, it is best to first plant a small area, and then, and then determine whether a large area is introduced, so it is more secure. Well, today's sharing is here, welcome to pay attention, like friends to like and then go.
