Problems solved by technology

In areas where the climate is dry, hot, and the temperature difference between day and night is large, the purchased seedlings have poor adaptability, short storage period, and high loss
[0005] It is difficult to adapt the maize breeding of the prior art to other areas, especially a kind of indoor maize cultivation method under high temperature and arid climate conditions, and its survival rate is low

Embodiment 1

[0017] A method for cultivating corn with high linoleic acid content, is characterized in that, comprises the steps:

[0018] (1) Preparation of culture soil: Take the culture soil of 2.5kg / m3 decomposed oil, add a mixture of vermiculite and peat soil in a weight ratio of 1:3, and add 4kg of lime per cubic meter to mix evenly, and expose to the sun Fermented and sterilized for 6 days;

[0019] (2) Fertilization for soil preparation: Open the furrows on the leveled cultivation site, the length and width of which are 1.5m, control the width of furrows to 0.3m, mix 1.3 parts of superphosphate and 1.5 parts of oil by weight evenly and decompose , and then apply the decomposed fertilizer to the open field according to the ratio of 700kg / mu;

[0020] (3) Planting: In the field after fertilization, ditches are made at a row spacing of 12 cm, with a ditch width of 4 cm and a ditch depth of 8 cm. The plant spacing is 6 cm, and the amount of cultivated corn per mu is 45 kg;

Embodiment 2

[0024] A method for cultivating corn with high linoleic acid content, is characterized in that, comprises the steps:

[0025] (1) Preparation of culture soil: Take 3 kg / m3 of decomposed oily soil, add a mixture of vermiculite and peat soil in a weight ratio of 1:3, and add 4.5 kg of lime per cubic meter to mix evenly, and expose to the sun Fermented and sterilized for 7 days;

[0026] (2) Fertilization for soil preparation: open the furrows on the leveled cultivation site, the length and width of which are 1.5m, control the furrow width of 0.4m, and mix 1.5 parts of superphosphate and 2 parts of oily dryness by weight evenly and decompose , and then apply the decomposed fertilizer to the open field according to the ratio of 700kg / mu;

[0027] (3) Planting: Ditch the row spacing of 12 cm in the field after fertilization, the ditch width is 5 cm, the ditch depth is 8 cm, and the plant spacing is 6 cm, and the amount of cultivated corn per mu is 45 kg;

[0028] (4) Growth perio...

Abstract

The invention discloses a culture method of high linoleic acid content maize. The method is characterized by comprising the steps of (1) preparing culture soil; (2) arranging the land and fertilizing; (3) planting; (4) managing in the growth period; (5) thinning. According to the method, the seeds are propagated, so that the quantity of maize used is reduced, the plant survival rate is high, and the seed output is high; in addition, the method is applicable to high-temperature drought weather condition; the planted maize is emerald green in leaf, high in diseases and pests resistance and high in linoleic acid content; therefore, the method has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of agricultural product planting, and in particular relates to a method for cultivating corn with high linoleic acid content. Background technique [0002] Linoleic acid is a fatty acid that cannot be synthesized by the human body, or the amount of synthesis is far from meeting the needs, called essential fatty acids. Linoleic acid is recognized as an essential fatty acid. Because linoleic acid can lower blood cholesterol and prevent atherosclerosis, it has attracted much attention. Studies have found that cholesterol must be combined with linoleic acid for normal operation and metabolism in the body. If there is a lack of linoleic acid, cholesterol will combine with some saturated fatty acids, resulting in metabolic disorders, depositing on the blood vessel walls, gradually forming atherosclerosis, and causing cardiovascular and cerebrovascular diseases. [0003] The linoleic acid content of corn reaches...
