Embodiment Construction

[0018] Maize is a high-yielding crop, and cultivation technology is the key measure to achieve high yield under suitable climatic conditions. The current corn production level in our region is 400-500 kg. Compared with the world, there is still a large room for increasing production. Through the experiments and demonstrations in recent years, we have obtained the following complete set of high-yield cultivation methods:

[0019] A high-yield cultivation method for summer corn, comprising the following steps:

[0020] 1. Seed selection, the inherent high yield of the selected species is better. The summer maize is the variety Huafeng No. 8 with vertical leaves or semi-vertical leaves.

[0021] 2. Pre-sowing treatment, one is sun-drying, 2-3 days before sowing, under sunny days, take out the seeds, spread them in the sun, and sun-dry them for 1-2 days, which can increase the germination potential and promote germination. The second is seed dressing or seed soaking. Use 10 ml...

Abstract

The invention relates to a cultivation method of crops, in particular to a high-yield cultivation method of high-yield high-quality and high-benefit summer maize. The high-yield cultivation method comprises the following steps of: seed selection: selecting Huafeng NO.8; treatment before seeding: 1, drying seeds in the sun; and 2, dressing seeds or soaking seeds; seeding at proper time, wherein the seeding time is between September 20 and September 25, and the number of plants per mu is 4000-4200; weed prevention and weeding of maize land: weeding after seeding and before emergence of seedlings; disease and insect pest prevention and control: evenly spraying Fuge in the period from the emergence of seedlings to 3-5-leaf stage; increase of fertilizing amount, wherein fertilizing amount per mu is 75 kg of multielement fertilizer; alternate-row castration and artificially supplementary pollination: artificially castrating one row every two rows when tassel just grows parietal lobe and does not loose powder and carrying out artificially supplementary pollination at the same time. The high-yield cultivation method of summer maize is simple and easy to implement and has hihg maneuverability, and the yield per mu of maize cultivated by the method provided by the invention is 550-600kg.

Description

technical field [0001] The invention relates to a cultivation method for crops, in particular to a high-yield cultivation method for summer corn with high yield, good quality and high benefit. Background technique [0002] Summer corn is a major food crop in our region. The annual planting area in our area is about 550,000 mu. With the continuous improvement of production level, farmers have higher and higher requirements for corn yield. In order to obtain higher yields, a set of more scientific and advanced cultivation techniques is required. The simple cultivation techniques in the past obviously cannot meet the needs of current agricultural production. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a high-yield cultivation method for summer maize with high yield, good quality and high benefit. [0004] In order to solve the above problems, the present invention adopts the following ...
