Introduction of peanut variety Wanhua 2 with a yield of 2000 jin per mu and key points of characteristic cultivation techniques of Wanhua 2

Peanut varieties are more, peanut planting time and planting methods are introduced; this Wanhua No. 2 variety peanut, do not know, then take a look at it!

Identification of disease resistance: identified by Plant Protection Institute of Henan Province Academy of Agricultural Sciences in 2009 and 2010: resistance to net spot (grade 2), susceptibility to leaf spot (grade 7), moderate resistance to rust (grade 5), moderate resistance to virus disease (incidence rate 23%), susceptibility to root rot (incidence rate 24%) in 2009; resistance to net spot (grade 2), susceptibility to leaf spot (grade 6), moderate resistance to virus disease (incidence rate 25%), susceptibility to root rot (incidence rate 22%) in 2010.

Quality analysis: 2009/2010 agricultural products quality supervision and inspection center (Zhengzhou) detection: protein content 26.99%/26.61%, crude fat content 48.65%/49.58%, oleic acid content 37.94%/40.8%, linoleic acid content 39.05%/37.2%, oil content (0/L)0.97/1.1.

Yield performance: In 2009, the regional trial of pearl bean peanut varieties was summarized at 9 points. The pod yield increased by 7 and decreased by 2. The average pod yield and seed yield per mu were 298.7 kg and 224.5 kg, respectively, which increased by 5.8% and 6.5% compared with the control Yuhua 14. The results showed that the pod yield increased significantly compared with the control. In 2010, the yield of pod was 302.2kg/mu and 226.4kg/mu, which were 14.4% and 13.7% higher than that of Yuhua 14, respectively.

In 2011 provincial production test, 7 points were summarized, all pods increased yield, the average yield of pods per mu was 298.5 kg, seeds per mu was 226.9 kg, which increased by 13.6% and 14.6% respectively compared with the control Yuanza 9102, ranking second and first among 6 tested varieties.

Suitable areas: Henan spring and summer planting.

Key points of cultivation techniques:

(1) Sowing date and density: from mid-April to early June, not too early or too late, plastic film mulching can be sown around April 10. Spring sowing 8000-10000 holes/mu, summer sowing 10000-12000 holes/mu, double seeds per hole, sowing should not be too deep, 3 cm is appropriate.

(2) Field management: apply about 40kg of three-element peanut fertilizer per mu, or 30-40kg of three-element compound fertilizer (15-15-15) plus 10kg of potassium chloride. During the growth period, Fuda peanut package management with front promotion, middle control and rear protection was adopted, and attention was paid to the prevention and control of diseases and insect pests to achieve high and stable yield, high quality and high efficiency.
