Introduction to the Characteristics and Traits of the Jimai 22 Wheat Variety

Edible Gardening 0 views
Characteristics and Traits: This variety is winter-type. The seedlings are semi-erect. It has good cold resistance, relatively strong tillering ability, and a relatively high spike-forming rate. It is a multi-spike type variety. The plant type is compact, the leaves are relatively small and erect, and the stems and leaves have relatively much wax. The plant height is 70-75 cm. The stems have good elasticity and strong lodging resistance. It has good comprehensive disease resistance. It yellows well, the spike is rectangular-ovoid, with long awns and white glumes. The grains are white, vitreous, and plump. In the 2003-2004 Shandong provincial regional trial mixed-sample determination, the test weight was 771 g/L. Yield components: 450,000-550,000 spikes per 667 sq m, 35.65 grains per spike, and 1000-grain weight 45 g. Its outstanding features are high yield potential, wide adaptability, and strong stress resistance. It is suitable for planting in medium- and high-fertility and high-water plots throughout Shandong. 2 Super-high-yield cultivation techniques 2.1 Apply more organic fertilizer, balance chemical fertilizer application, and build up soil fertility. Building up soil fertility: According to research by the Henan @#@245@#@ High-Stable-High-Yield-Low-Cost Cooperative Group, for super-high-yield wheat with a yield above 600 kg per 667 sq m, the dependence rates on soil nitrogen, phosphorus, and potassium nutrients were 82.8%-85.9%, 91.7%-95.1%, and 85.1%-88.3%, respectively, much higher than the dependence rates on soil nitrogen, phosphorus, and potassium nutrients of high-yield wheat fields with a yield of 500 kg per 667 sq m (between 65% and 80%). This indicates that achieving super-high yield in wheat requires fertile soil as a guarantee.
