Problems solved by technology
Crops do not require much molybdenum, but if it is lacking, it will seriously affect the normal growth of crops, and excessive application of molybdenum fertilizer will cause harm to crops or excessive molybdenum accumulation in crops will produce feed that is toxic to animals, causing soil environmental pollution and water pollution
Molybdenum content in the soil in the hilly areas of Sichuan is generally low, the light intensity is weak, and the soybean yield is low. Therefore, a fertilization method for interplanting summer soybeans with high-stalk crops is provided to solve the problem of weak seedlings, Problems such as low photosynthetic efficiency and low yield have important practical significance for the development of my country's interplanting soybean production and the protection of my country's food security

Embodiment 1
[0044] Experimental site: Teaching farm of Sichuan Agricultural University.
[0045] Test group: corn and summer soybeans were planted in strips, with a 2m open box, corn and summer soybeans each accounted for 1m, 2 rows of corn were planted and 3 rows of soybeans were planted, the distance between summer soybeans and corn was controlled at 33cm, and the corn variety Chuandan 418 was Sowing on April 8, the nest spacing is 45cm, and two nests are left; the summer soybean variety Gongxuan 1 was sown on June 4, with a row spacing of 33cm and a nest spacing of 30cm, with two nests remaining. The effective molybdenum content and the weight ratio of seeds are set at 4 levels for seed dressing, which are 0.5g / kg, 1g / kg, 2g / kg and 4g / kg respectively; the effective nitrogen application rate in the three-node stage of summer soybean is 6kg / mu, which is effective Phosphorus application rate is 35kg / mu, effective potassium application rate is 6kg / mu, and other cultivation and management m...

The invention relates to the technical field of crops cultivation, in particular to a fertilizing method for interplanted summer soybeans and long-stalked crops. The fertilizing method comprises the step that summer soybean seeds per kilogram and molybdenum fertilizer with the effective molybdenum content being 1-2g are mixed for seed dressing and sowing. The root nodule quantity of the summer soybeans can be effectively increased, the chlorophyll content of the summer soybeans can be improved, the nitrogen content of leaves and the net photosynthetic rate of the summer soybeans are improved, the yield of the summer soybeans are improved, and the income of farmers is increased.
Description
technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a fertilization method for interplanting summer soybeans and high-stalk crops. Background technique [0002] Soybean has high nutritional value and is rich in nutrients such as protein and fat that can be easily absorbed and utilized by the human body. In recent years, my country's soybean imports have been increasing year by year, reaching 54.8 million tons in 2010, with a foreign dependence of more than 70%. The fact that soybeans are heavily dependent on imports threatens my country's food security. my country's arable land resources are limited, the population is growing rigidly, and the contradiction between people and land resources is becoming increasingly prominent. Therefore, the development of soybean planting in my country can improve soybean yield, increase land yield and improve resource utilization efficiency, alleviate the contradiction between human and l...
