In August 2003, the "Wangjiaba" trademark was registered, which is specially used for the production and processing of agricultural products. Wangjiaba Huaiyam has been included in the "Compendium of Materia Medica".

Upland rice is an excellent variety with good taste and rich nutrition. The various trace elements contained in rice fat are much higher than those of rice. It has high yield, is drought-resistant and flood-resistant, and is very suitable for planting in this region.

Peanut cultivation has been a pillar industry in Wangjiaba for many years. It has excellent varieties, good color and high oil content. It is favored by consumers and has great market potential. The growing period is from June to mid-October. The average yield per mu is 300-400 kilograms, and the price is 2-3 yuan/kg. The planting area is expanding year by year, with an annual planting area of ??more than 10,000 acres and a total output of more than 3 million kilograms.

The soil in Wangjiaba Town of Edamame is fertile and the water source is sufficient. There is no need to use chemical fertilizers or pesticides to grow edamame.

Urea and compound fertilizers, no pests during the growth period, no need to apply pesticides, it is a true green food. According to Lang Kegong, the secretary of Langwan Village, the yield of green onions is high. The average yield per mu is about 6,000 kilograms. This year’s market price is 1.4 yuan/kg, 0.4 yuan higher than last year. The output value per mu is more than 8,000 yuan. Excluding early investment such as seedlings and chemical fertilizers, the net output per mu is 1.4 yuan per kilogram. The income is more than 6,000 yuan, and green onions and edamame can be grown on each other's land, which also reduces idle land resources. It is really a good project for farmers to get rich.
