Which corn varieties have good tolerance to dense planting? Introduction to dense-planting corn varieties

Corn is an economic crop grown in many regions of our country. When planting corn, we all know that generally the more you plant, the higher the yield, but if you plant too many, there are many adverse effects on corn growth. Therefore, if you want dense planting, it is best to choose dense-planting corn varieties. Below is an introduction for everyone.

1. Nongda 372

The Nongda 372 variety has characteristics such as high yield, stable yield, excellent quality and strong resistance. Its average yield per mu reaches 691.1 kg, and it has good tolerance to dense planting. The planting density is 4500-5000 plants per mu, and even at 6000 plants per mu there will be no empty stalks.

2. Aidan 268

The advantages of the Aidan 268 corn variety are short plants, low ear position, disease resistance and lodging resistance, suitability for dense planting, and suitability for mechanical harvesting. In some test fields in Liaocheng, Shandong, Xinxiang, Henan and Jingxian, Hebei, the planting density is 6000-7000 plants per mu, with a maximum of 9000 plants, and the average yield per mu is 2050 jin.

3. Liangyu 99

The Liangyu 99 corn variety has strong tolerance to dense planting. Liangyu 99 is indeed a non-homogenized dense-planting type variety of a different category. If there are 200 more plants than the control variety, it will at least maintain equal yield; with 500 more plants, the comprehensive stress resistance remains unchanged, and the yield increases by at least 10% or more.

4. Yudan 9953

The planting density of Yudan 9953 is 5200-6700 plants/mu, with the optimal planting density being 5000-5500 plants, and high-water-and-fertilizer plots can reach 6000 plants . Under the density condition of 5000-5500 plants/mu, the field plants grow neatly, the ears inside and outside the population are uniform and consistent, there are no empty plants or barren tips, the kernel setting is good, the ears are uniform, and the grains are plump.

5. Hongrui 2081

Hongrui 2081 has characteristics such as early maturity, tolerance to dense planting, fast dehydration, drought resistance, lodging resistance, large ears and deep grains, and high yield. The suitable planting density is about 5000-6000 plants per mu, and the yield is generally 1600 jin per mu.

6. Nongda 488

The Nongda 488 corn variety has characteristics such as large ears under sparse planting and high yield under dense planting, but the planting density is generally best controlled at 3800-4000 plants/mu, and the planting density for high-water-and-fertilizer mu can be adjusted to 4000-4500 plants/mu.

Of course, in addition to the corn varieties introduced above, there are many other corn varieties that are also suitable for dense-planting cultivation. Is there anything else you would like to add about dense-planting corn varieties?
