Description

A kind of high oil corn high-yield cultivating method
Technical field
The present invention relates to a kind of cultivating method of crop, relate in particular to a kind of high oil corn high-yield cultivating method.
Background technology
High oil corn is that a kind of grain oil content of cultivating is than the high Types of Maize more than 50% of conventional corn.The oil content of conventional corn is generally 4%~5%, and the oil content of high oil corn is up to 7%~10%, makes corn from simple grain or forage crop has become oily grain or oil is raised crop, has greatly improved the economic benefit of maize planting.Simultaneously, high oil has also brought high protein, high-lysine, homovitamin A and high-energy, corn oil about 85% concentrates on embryo section, and high oil corn has a large embryo, the Embryo protein content of corn is higher 1 times than endosperm, lysine is high more than 2 times, the heat production value of corn oil is 2.25 times of starch, so comparing with conventional corn, high oil corn not only increased production oil, protein, lysine, vitamin A have been increased production simultaneously, have potential high-energy, the corn vitamin A increases regularly along with the raising of oil content.The oil production of high oil corn can be suitable with soybean oil production of the same area.The value of high oil corn is mainly manifested in the corn oil of being squeezed out by maize germ, and this oil is not only nutritious, and also has certain medical value, is the senior vegetable oil of deeply liking for the consumer.
The quality of edible oil quality is mainly seen the size of what and proportion of various content of fatty acid in the oil.The fatty acid that contains in the vegetable oil mainly contains: palmitic acid (claiming again palmitic acid), stearic acid, oleic acid (18 carbon monoenoic acid), linoleic acid (octadecadienoic acid), linolenic acid, erucic acid etc., various fatty acid proportion in different vegetable oil is different.Wherein, oleic acid, the edible oil quality that linoleic acid content is high are better, and linoleic acid is the constituent of cell membrane, and atherosclerotic and hypertension that hypercholesterolemia is caused have certain curative effect.The diseases such as hypercholesterolemia, arteriosclerosis, hypertension generally are to deposit at arterial wall because of cholesterol too much in the blood, and arteriosclerosis is caused.Linoleic acid and cholesterol are in conjunction with producing the low melting point lipid material, and this material is mobile in blood vessel easily, break away from arterial wall and reach the purpose that reduces cholesterol level, softening blood vessel.Different greases are different on the impact of cholesterol level in the human serum, and edible animal oil, particularly butter improve the content of cholesterol in serum widely.Vegetable oil has the effect that reduces in various degree cholesterol level, wherein reduces at most with corn oil and safflower oil, and sunflower takes second place.Linoleic content is also high in soybean oil and the cottonseed oil, but large not as good as corn oil to the effect that reduces cholesterol level.This be because, except linoleic acid, also contain the compositions such as orizanol (oryzanol), phytosterol in the corn oil, the effect that reduces cholesterol level is arranged.These compositions and linoleic acid combination, and with the vitamin E acting in conjunction, greatly improved the ability that corn oil reduces cholesterol.The corn main body of oil is two kinds of unsaturated fatty acids of linoleic plus oleic acid, and content is respectively 26.6% and 58.7%,, and saturated fatty acid (mainly being palmitic acid) only is 11.5%.
In vegetable oil commonly used, the content of lipovitamin E is with corn oil the highest (938 mg/kg, cottonseed oil 68.2 mg/kg, soybean oil 49.2 mg/kg, peanut oil 44.4 mg/kg, rape seed oil 44.1 mg/kg).Vitamin E is a kind of natural antioxidant, the two not oxidized effects of key of protection linoleic acid is arranged, the storage life that has prolonged corn oil.Vitamin E has many-sided regulating action to body metabolism simultaneously, as accelerating the cell division breeding, prevent cell ageing, keeping human body Youth and longevity etc., can also suppress lipid peroxide and precipitate the formation thrombus in blood vessel, prevents arteriosclerosis.The E that is deficient in vitamin can cause the dysfunction of digestive system, urinary system, also can cause anaemia, hormone metabolism disorder, and damaging function and fecundity.Also contain more vitamin A in the corn oil, the effect with the xerophthalmia of preventing, nyctotyphlosis, dermatitis, bronchiectasis and cancer.In addition, also contain sitosterol and lecithin in the corn oil, the former has the effect of anti-asthma, prevention wrinkled skin, and the latter has the reduction cholesterol, enhances memory, improves the effect of brain function.
Corn oil after concise is the edible oil of high-quality, and good taste is of high nutritive value, have higher can value, be the outstanding person in each vegetable oil.The calorific value of corn oil is 9413 kcal/kg, and the calorific value of sesame oil is 9330 kcal/kg, and siritch is 9364 kcal/kg, and peanut oil is 9410 kcal/kg.Corn oil is low because of fusing point, is easily absorbed by human body, and absorption ratio can reach more than 98%, and that the corn oil after concise is is golden yellow, not muddy, free from admixture, good, the free from extraneous odour, not perishable of the sense of taste, is human comparatively ideal edible vegetable oil.
Corn is topmost feed resource, but because the protein content of conventional corn is lower, lysine do not have or content extremely low, must add the auxiliary material of doing that soybean etc. contains high protein, cause feed cost higher.And generally, one ton of high oil corn is than 15~20 kilograms of protein of conventional corn fecund and 1~2 kilogram of lysine.The quantity of heat production of corn oil is 2.25 times of starch, can solve the problem of selling at exorbitant prices with high oil corn.Related tests shows, feeds the high oil corn feed in the sow gestation phase and compares with feeding the conventional corn feed, can significantly increase sow body weight and body fat content, increases milk yield and piggy survival rate.High oil corn is fed laying hen, and its egg is raised than being significantly higher than conventional corn; The high oil corn feed can not add fat, and corn oil not only absorbs easily, and helps absorbing of liposoluble substance.
In sum, the plantation high oil corn is benefited the nation and the people, but has no technology or the related data report of scale cultivation high oil corn in the prior art.
