The size of the corn ear directly determines the yield of corn, and varieties with large fruit ears and many grains can obtain high yields. Today I will introduce you to a new variety of oversized ear corn. This breed is the Qiangshuo 88.
Qiangshuo 88 is a new variety of corn selected by Dalian Academy of Agricultural Sciences, which passed the examination and approval of Liaoning Province in 2011 and the Huanghuaihai Summer Corn District in 2020. As well as Gansu Province and Hubei Province, it can be cultivated in most of the northern provinces of China. What are the outstanding features of this variety?
The fruit spikes are oversized
Qiangshuo 88 is a new variety of large ear maize, the fruit panicle is conical, the panicle length is 20 to 27 cm, and the panicle thickness is 5.1 cm. The number of panicle rows is 16 to 22 rows, up to 24 rows, the number of rows is 38.7 grains, the panicle shaft is red, the grain is yellow, semi-purslane type, and the weight of 100 grains is 38.4 to 40.31 grams. The fruit panicle size is uniform.
Good overall disease resistance
After inoculation identification, it is resistant to ear rot, medium resistance to stem rot, small spot disease, Curvularia leaf spot disease and southern rust, fruit ear buds are tight, resistant to corn borer is prominent, especially this year in the rainy situation, showing very good rust resistance. Live trees are ripe and the grains are well-rounded.
Drought resistant
Qiangshuo 88 Huanghuaihai area summer sowing, the average plant height of 277 cm, panicle height of 119.3 cm, adult leaves 21 ~ 22 pieces, stem thick elasticity is good, the root system is developed, gas rooting more, firm grip, not only good drought resistance, but also high resistance to lodging.
Stable and high yield
Qiangshuo 88 has good adaptability and high yield, summer sowing in The Huang-Huai-Hai region, the general average yield is 1400 jin per mu, and the highest mu yield can reach 2230 jin, and the spring sowing in Gansu Province has an average yield of 2079 and 6 jin per mu, and the highest mu yield can reach 2500 jin. It is a new variety of corn with stable yield and high yield.
Cultivation technique points
Qiangshuo 88 spring sowing is generally from late April to early May, 4000 seedlings per mu, summer sowing in the Huang-Huai-Hai region, the best sowing period is From May 20 to June 15, 3800 to 4000 seedlings per mu are used for seed fertilizer sowing, the spacing between seed fertilizers is 8 to 10 cm, the foot is sown, to ensure that a whole seedling is sown, and the control agent is sprayed at the 5 to 8 leaf stage, and the chemical control is carried out to prevent lodging. 20 kg of urea per mu is applied in the big horn mouth stage, and attention is paid to the prevention and control of corn borers, aphids and other diseases and insect pests in the middle and late stages of growth.
