Embodiment 1

[0022] A method for planting chromium-rich corn, the specific steps are as follows:

[0023] (1) Land preparation and fertilization: Choose a soil with good drainage and rich nutrition, apply compound fertilizer A 18kg / mu, turn 25~30cm deep, raking and leveling, evenly apply organic fertilizer 800kg / mu, laying sprinkler irrigation pipes, one every 5m facility The sprinkler irrigation port can be sprayed with water or chemical fertilizer solution, spraying 70kg / mu of water, covering with mulching film for 8 days, killing the pests in the soil, and waiting to be planted;

[0024] (2) Seed selection: select high-yield, disease-resistant, and full-grained corn seeds, spray the corn seeds with a germinating agent solution of 28% of the weight of the corn seeds evenly before planting, mix them evenly, and cultivate at a constant temperature of 25°C and a humidity of 76% Place it in the box for 20 hours to increase the germination rate and shorten the germination time, so that corn seeds ...

Embodiment 2

[0036] A method for planting chromium-rich corn, the specific steps are as follows:

[0037] (1) Land preparation and fertilization: choose soil with good drainage and rich nutrition, apply compound fertilizer A 19kg / mu, turn 25~30cm deep, raking and leveling, evenly apply organic fertilizer 850kg / mu, lay sprinkler irrigation pipes, one every 6m facility The sprinkler irrigation port can be sprayed with water or chemical fertilizer solution, spraying 73kg / mu of water, covering with mulching film for 8 days to kill pests in the soil and wait for planting;

[0038] (2) Seed selection: select high-yield, disease-resistant, and full-grained corn seeds, spray the corn seeds with a germinating agent solution of 29% by weight of the corn seeds evenly before planting, mix them evenly, and place them in a constant temperature culture at 26℃ and 77% humidity. Place it in the box for 21 hours to increase the germination rate and shorten the germination time, so you have to plant corn seeds;

Abstract

The invention relates to the technical field of planting and discloses a planting method for chromium-rich corn. The method comprises the steps of preparing soil and fertilizing, selecting seeds, sowing corn, managing water and fertilizer and preventing and controlling diseases and pests. According to the planting method for chromium-rich corn provided by the invention, sufficient base fertilizer is applied to the soil; the fertilizer ratio is proper; the soil is covered with a soil film and is fermented; the harmful diseases and pests are killed; the germination rate of the corn is 99-100%; the seeds are subjected to bud forcing treatment; the germination period is reduced by 2-3 days; the separate planting based on density is performed; the row spacing of the close planting set is small; the row spacing between the close planting set and the close planting set is larger; the ventilation is benefited; the land utilization is saved; the corn yield is increased to 846kg / mu; the thousand seed weight of the corn is 347g; the water and fertilizer management is performed in stages; the traditional Chinese medicine insecticide is periodically applied; water and fertilizer are saved; the disease and pest ratio is 4%; 16.3% of the planting cost is saved; the compound fertilizer is rich in chromium element; the chromium content in the corn is increased to 54.87ng / 100g; the corn grade is promoted; the nutrition and healthcare function of the corn are enhanced.

Description

Technical field [0001] The invention mainly relates to the field of planting technology, in particular to a planting method of chromium-rich corn. Background technique [0002] Corn, also known as maize, bun, corn, and cob, is an annual grassy herbaceous plant. It is an important food crop and an important source of feed. It is also the world's highest yield food crop. Corn is rich in nutrition, rich in dietary fiber, protein, vitamins and mineral elements. Among the more than 50 kinds of nutrition and health substances that have been proven to be the most effective today, corn contains 7 kinds: calcium, glutathione, cellulose, magnesium, and selenium. , Vitamin E and fatty acids, can be used for skin care, weight loss, lower blood pressure, lower blood fat, enhance memory, anti-aging, protect eyesight, promote gastrointestinal function, inhibit cancer and fight cancer. [0003] Chromium is one of the indispensable trace elements in the human body. The absorption and utilization r...
