Problems solved by technology
[0003] Through the above analysis, the problems and defects in the prior art are: the existing planting method is affected by climate change and planting structure adjustment, and the yield is low
[0004] The difficulty in solving the above problems and defects is: late spring cold is a common weather condition in the Yangtze River Basin. Generally, it can be solved by covering the plastic film, but the plastic film is difficult to recover and the plastic pollution is serious, and there is no good solution. Therefore, through accurate Grasping the planting time, reducing or eliminating the use of plastic film from the source are effective means to reduce microplastic pollution

Embodiment 1
[0048] Applicable areas: Jianghan Plain and the middle and lower reaches of the Yangtze River
[0049] Cultivation mode: "grain-silage-green manure"
[0050] Corn varieties: middle-early-maturing varieties are selected for grain, and silage corn is not limited.
[0051] Fertilization: apply N:P per mu 2 o 5 :K 2 O=17.5:6.0:6.0kg.
[0052] Fertilizer selection: equal ratio compound fertilizer (15:15:15 or 18:18:18), ordinary urea, and controlled release urea with a controlled release period of 60 days. The ratio of controlled release urea to normal urea is 1:1.
[0053] Taking 15:15:15 compound fertilizer as an example, the calculation is as follows:
[0054] Compound fertilizer 40kg, ordinary urea 12.5kg, controlled release urea 12.5kg. All fertilizers are mixed evenly and used at one time.
[0055] Selection of green manure varieties: Mixed sowing of light-leaf sweet potato / fat field radish / ryegrass, the dosage of light-leaf sweet potato, fat field radish and ryegrass a...

The invention belongs to the technical field of agriculture planting, and discloses a two-season maize cultivating method and fertilizing method for sowing, digging, pressing and applying green manure. A two-season maize cultivating method for sowing, digging, pressing and applying green manure comprises the steps of reasonably arranging two-season sowing time, applying green manure and performingsowing, and according to a culturing mode of sowing grains in spring, performing silage in autumn and performing mixed sowing of green manure, and according to the time of sowing grains in spring andperforming silage in autumn, performing two-season maize-green mature cultivating. Comprehensive factors of weather conditions (being cold in the air in early spring, rainy in seasons and being drought during hot summer days ), improvement of soil fertility and the like are comprehensively considered, a method for reasonably arranging two-season sowing time and sowing green manure, is adopted, the culturing mode of sowing grains in spring, performing silage in autumn and performing mixed sowing of green manure is provided, and a method for reducing quantity of applied manure in the mode, andapplying the manure once, is provided. Under the condition that original planting areas are guaranteed to be unchanged, the yield of maize is increased, and besides, the usage quantity of the manure is saved.
Description
technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for two-season corn cultivation and fertilization by pressing green manure. Background technique [0002] At present, affected by climate change and planting structure adjustment, the planting area of rice in the middle reaches of the Yangtze River has been decreasing year by year, and the planting area of corn has been increasing year by year. Considering the natural conditions of heat and water, two crops of corn can be cultivated in the Jianghan Plain, but due to late spring cold and summer drought Frequent occurrences lead to high cultivation technology requirements, so the actual cultivation area has not expanded. Late spring is a common weather condition in the Yangtze River Basin. Generally, it can be solved by covering plastic film. However, it is difficult to take back the plastic film and the plastic pollution is serious, and there...
