Embodiment Construction
[0019] The operation and effect of the technical solution of the present invention will be further described below.
[0020] (1) Soil testing and formulating sufficient base fertilizer: According to the basic conditions of cultivation soil fertility and measuring the existing nitrogen, phosphorus, and potassium contents in the soil, reasonably plan the output, and apply a reasonable formula to apply sufficient base fertilizer according to the planned output and soil fertility.
[0021] (2) Timely sowing: According to the moisture content of the plot, sow in time during the suitable sowing period.
[0022] (3) Keep double seedlings in each hole, about 4400 seedlings per mu: the traditional sparse planting cultivation method is single plant, 2900-3200 seedlings per mu, and the light rate can reach 50%, but because of the small number of plants, The yield per mu can only reach about 650 kilograms. At present, the common cultivation method of densely planted corn leaves 4400-4500...

Abstract
A cultivation method for corn leaf age management, including soil testing and formulating sufficient base fertilizer, timely sowing, leaving two seedlings in each hole, about 4400 seedlings per mu, inspecting and replenishing seedlings at the 3-5 leaf stage, spring sowing corn in the 5-9 leaf stage, re-sowed corn at the 5-8 leaf stage to reduce, squat seedlings, and increase light; spring sowed corn at 9-12 leaf stage, re-sowed corn at 8-10 leaf stage, topdressing and watering; spring sowed corn At the 18-leaf stage, the re-sowed corn is poured with relay water at the 16-leaf stage. The present invention changes the extensive mode of field management in the past to leaf age management. According to the growth characteristics of corn, fertilization, watering, and intertillage are applied according to leaf age during the growth period of corn, and topdressing is carried out in the best period of plant growth to achieve water and light. Reasonable utilization of nutrients such as air, heat, etc., compared with traditional sparse planting cultivation methods and dense planting cultivation methods, can achieve better light receiving rate, air permeability and leaf area index of corn, so that various cultivation management measures can be achieved in time and effect. On the premise of increasing the output per unit area, the economic benefits have also been improved.
Description
technical field [0001] The invention belongs to the technical field of crop cultivation and management, and in particular relates to a cultivation method for leaf age management of corn. Background technique [0002] my country is a big corn-producing country, and corn accounts for a quarter of the country's grain output, and it is the main source of income for farmers in major corn-producing areas. Corn economy has become one of the leading factors in regional economic development. Corn is not only rations and feed, but also an important industrial raw material. With the development of agricultural and sideline products processing industry, corn has more and more uses, and its consumption and demand are increasing. [0003] The yield per unit area of corn in my country varies greatly. Even in the same ecological environment, due to different cultivation and management methods, the difference in yield per unit area is one to two hundred kilograms. Therefore, it is very po...
