Introduction of Bainong 4199 varieties

Many people do not know what this is when they first see the Bainong 4199 variety, and those who have known it a little may not be very clear, so let's take a look at the introduction of the Bainong 4199 variety.

Introduction of Bainong 4199 varieties

Bainong 4199 is the first wheat variety with high light efficiency in China, which was selected by scientists through the directional breeding of the high light efficiency material Bainong Gao Guang 3709F2 and Ai Kang 58.

Bainong 4199 wheat is a semi-winter mid-early maturing variety, which has good cold resistance and disease resistance, so it is suitable to be planted in Henan province (except the wheat area of the middle and lower reaches of the Yangtze River in the south).

The whole growth period of Bainong 4199 wheat is 229.0 to 230.9 days. Seedlings semi-prostrate, short and wide leaves, dark green leaves, general tillering ability, high panicle rate, early jointing in spring, fast polarization, early heading; compact plant type, small flag leaves, plant height 68.1-75.0 cm, weak stem elasticity, general lodging resistance, sensitive to low temperature in spring, empty tip phenomenon; spindle-shaped ear, upper ear code is dense, long awn, white shell, white grain, horny, grain plumpness Can not bear high temperature in the later stage, and the mature phase is general.

From 2015 to 2016, the Institute of Plant Protection of Henan Academy of Agricultural Sciences was inoculated and identified as moderately resistant to stripe rust, moderately susceptible to leaf rust, powdery mildew and sheath blight, and highly susceptible to scab.

2. Cultivation techniques of Bainong 4199 wheat

1. Sowing date

The sowing date is from October 5 to 15.

2. Seeding quantity

The sowing rate of high fertility plot is 70.8 kg per mu, and the medium and low fertility can appropriately increase the sowing rate. For example, it is appropriate to increase the sowing rate by 0.5 kg every 3 days for delayed sowing. Planting with equal row spacing of 6 to 7 inches.

3. Fertilization

Foot fertilizer, the general amount of fertilizer per mu, pure nitrogen 12 kg, phosphorus pentoxide 7.5 kg, potassium oxide 7.5 kg; after jointing, 6 kg urea per mu.

4. Pest control

Chemical control was carried out at jointing stage combined with chemical weeding in the field to reduce plant height; at heading and flowering stage, fungicides such as carbendazim or methyl thiophanate wettable powder were sprayed in time to control scab, and potassium dihydrogen phosphate was sprayed at filling stage.
