Introduction of Wheat Variety Zhengmai 136
1. Cold tolerance
The seedlings are semi-prostrate, with narrow and short leaves, yellow-green leaves and strong tillering ability. It started jointing late in spring, but it polarized quickly and had strong resistance to late spring cold. It belongs to semi-winter wheat variety.
2. Short pole anti-toppling
Zhengmai 136 has an average plant height of 74.7-80.4cm, compact plant type, good stem elasticity, thick waxy layer, raised flag leaves and strong lodging resistance.
3. Strong disease resistance
After identification, the quality is high and resistant to stripe rust, moderately susceptible sheath blight, powdery mildew and leaf rust. Moderate resistance to scab. The comprehensive disease resistance is good, and the application amount of pesticides can be reduced.
4. The peak is big and even
Zhengmai 136 is a new wheat variety with big spike type, with spindle-shaped spike type, long awn, white shell and white grains, and half-corner plasmid, and good plumpness. The number of ears per mu is 41.3-449,000, the number of grains per ear is 30.2-34.2, and the 1000-grain weight is 44.6-47 grams.
5. Output performance
202 1, agricultural experts calculated the yield of Zhengmai 136. The theoretical yield is 840.2 kg, which is equivalent to 15% discount, and the converted yield per mu is 7 14.2 kg.
6. Growth period
The whole growth period is 230-233 days, which is slightly earlier than the maturity of the control variety Zhoumai 18.
Second, the key points of cultivation techniques
1. Soil requirements
The land is flat, the soil surface is soft, the cultivated layer is deep, and the sand viscosity is moderate. When plowing, you should rake the clods to make them flat and solid.
2. Key points of fertilization
The application amount of base fertilizer should account for about 70% of the total fertilization amount. Generally, 100 kg of commercial organic-inorganic compound fertilizer, 40 kg of 45% ternary compound fertilizer and 10 kg of urea are applied per mu, which are applied before ploughing and evenly applied to the soil by mechanical operation.
3. Sowing time
Sowing in the first half of June, 16- 18℃.
4. Prevention of diseases
Pay attention to the prevention and control of aphids, leaf rust, stripe rust, scab and sheath blight when planting. 200g of 99% potassium dihydrogen phosphate and 0.0 1% brassinolide soluble agent10ml can be added per mu for mixed spraying of medicine and fertilizer.
Weed control
Pull out gramineous weeds in time. Weeds can be treated by special spraying.
6. Regional selection
Wheat areas in the north-central part of Henan Province, including Xuchang, Zhengzhou, Luoyang and irrigated land north of the Yellow River; The wheat-growing areas in central and eastern Henan Province include irrigated land in the middle and northern Zhumadian, Luohe, Zhoukou, Shangqiu and eastern Pingdingshan. It is a high-yield semi-winter variety with certain water saving and drought tolerance.
Zhengmai 136 is not only resistant to diseases and cold, but also has yield advantages, bright seeds, full horniness, good commodity and easy to sell. The price is 3-5 cents higher than other wheat, and the disaster year is basically stable, and it is not affected by diseases and freezing damage.
