Abstract

A method for cultivating selenium-rich psidium guajave trees mainly comprises the steps that selenium, nitrogen, potassium, phosphorus and molybdenum are mixed with water according to a certain proportion for preparing a nutrient solution, the nutrient solution is sprayed and applied in the proper period when the psidium guajave trees bloom and bear fruits, and the psidium guajave is made to be rich in selenium after maturing. According to the method, inorganic selenium and chromium are converted into organic selenium through absorption of the psidium guajave, the psidium guajave is not poisonous, and crops have the effects of high disease suppression performance, yield increasing and psidium guajave quality improving. The content of selenium of produced psidium guajave juice reaches 4.1 mg/kg, the content is stable, the psidium guajave is rich in nutrient, and the psidium guajave or the psidium guajave juice is made to be real nutrient and health care food. Meanwhile, the channel for planting the psidium guajave trees is innovated for fruit farmers, and the income is increased.

Description

A kind of cultivation method of rich selenium guava fruit tree

Technical field

The present invention relates to a kind of cultivation method of rich selenium guava fruit tree.

Background technology

Selenium-enriched food has also progressively been popularized by people's understanding and has been eaten and bring health, away from " three is high sick ".Developing rich selenium organic health agricultural product, is modern agricultural development increment only way.According to disclosed document announcement: selenium is called " king of health care " by scientist, in vivo with vitamin E synergy, can Cell protection film, prevent the oxidation of unsaturated fatty acid, thus selenium has antioxidation.Selenium also has develop immunitypty: Organic Selenium can remove interior free yl, gets rid of vivotoxin, anti-oxidant, the generation that effectively can restrain lipid peroxide, prevents blood clot, remove cholesterol, strengthen immune function of human body.Prevent and treat diabetes, replace islet function, activate islet cells and normally work, it can prevent beta Cell of islet Oxidative demage, makes its function normal, promotes sugared part metabolism, reduces blood sugar and glucose in urine, improve the symptom of diabetic.Selenium also has and prevents cardiovascular and cerebrovascular disease: selenium is the important element maintaining heart normal function; to the effect that heart human body has protection and repairs; blood fat, blood pressure can be lowered, reduce myocardial infarction area; the reduction of human body blood selenium level; the hypofunction of scavenging free radicals in body can be caused, cause hazardous material deposition to increase, blood pressure raises, vascular wall is thickening, blood vessel elasticity reduces, VPV is slack-off; send oxygen function reduction, thus the incidence of disease bringing out cardiovascular and cerebrovascular disease raises.Therefore supply Se scientific has good effect, so authoritative health organization suggestion, human body should increase 100ug-200ug selenium every day to prevention cardiovascular and cerebrovascular disease, hypertension, arteriosclerosis etc.

Guava comes from Compendium of Material Medica the 459th page of brief introduction: smell, and sweet, sour, puckery, warm, nontoxic, cure mainly throat yearningly dry, waist pin is unsuccessful, only diarrhea and involuntary emission.People often buy the Fructus psidii guajavae immaturus juice product such as guava bar, guava block in the market, but not containing selenium element, just normal food.There is not rich selenium guava juice production method open at present, market there is not yet rich selenium Fructus psidii guajavae immaturus or fruit juice list marketing.

" Baidu " introduces modern study, and guava is nutritious, and Vitamin C content is high.Fruit has treatment diabetes and hypoglycemic drug effect, and blade also can control diarrhoea.Fruit, except eating raw, also can be processed into fruit juice, inspissated juice, fruit powder, jam, thickened pulp, jelly etc.Guava pericarp is thin, yellow green, and pulp is thick, fresh and sweet crisp and refreshing, and the little seed of the heart is little, and fruits nutrition enriches, and containing the higher trace element such as vitamin A, C, cellulosic and phosphorus, potassium, calcium, magnesium, fruit is also rich in protein and lipid in addition.Often eating can be anti-aging, discharges vivotoxin, enhances metabolism, regulates physiological function, often guarantor healthy, is the best fruit of diabetic.

Unstable and the qualified products can not produced by national standard requirements of rich selenium agricultural byproducts content in the market, develop the new model that Se-rich farm products is modern agricultural development wound value farmer richness.

Summary of the invention

The object of this invention is to provide and a kind ofly can effectively carry selenium-enriched content, and make the cultivation method of the rich selenium guava fruit tree of its stable content.

The technical solution adopted in the present invention is: by following ratio of weight and number composition: selenium 0.04-0.09, nitrogen 1.5-3.0, potassium 1.6-3.2, phosphorus 1.7-3.8, molybdenum 0.1-0.3 and water 1100 are hybridly prepared into nutrient solution.Respectively drench root once at bloom the last week and Post flowering one week of guava, and fruit expanding period foliage-spray three times, spray interval time is 13 days at every turn, is namely rich in selenium element after guava maturation.

Inorganic selenium, chromium are Organic Selenium by guava sorption enhanced by the present invention, not only nontoxic, and make crop have stronger press down sick, increase production, improve the effect of guava quality.

Beneficial effect of the present invention is as follows: the present invention adopts conversion technology, nutrient solution (containing selenium element) is adopted to bloom the last week and Post flowering one week each pouring root once in finite concentration ratio guava in breeding time to guava, and fruit expanding period foliage-spray three times, absorb by guava root, leaf, fruit portion, conduct, transform, inorganic selenium is changed into and is rich in Organic Selenium, and improve its content.The content of the rich selenium of the guava juice made of it is up to 4.1 mg/kg, and its stable content, nutritious, make Fructus psidii guajavae immaturus or fruit juice become a kind of real nutritional health food, simultaneously for orchard worker plants guava innovation channel, increase income.

embodiment:

The present invention's three kinds of ratio nutrient solution embodiments are as shown in the table:

Above composition mixed preparing forms nutrient solution.Respectively drench root once at bloom the last week and Post flowering one week of guava, and fruit expanding period foliage-spray three times, spray interval time is 13 days at every turn.

Again by rich selenium guava according to the following steps: choosing fruit → clean → squeeze the juice → filter → bottling, rich selenium guava juice.

The present invention sprays with rich selenium element high concentration nutritional liquid within guava vegetative period, organic selenium content is made to improve the content reaching needs, guava is processed into the content of selenium after fruit juice up to 4.1 mg/kg, allocate by product standard quality, make guava juice product remain stabilised quality, reach qualified products requirement.

Claims

1. the cultivation method of a rich selenium guava fruit tree, it is characterized in that following ratio of weight and number composition: selenium 0.03-0.09, nitrogen 1.5-3.0, potassium 1.6-3.2, phosphorus 1.7-3.8, molybdenum 0.1-0.3 and water 1100 are hybridly prepared into nutrient solution, respectively root is drenched once at bloom the last week and Post flowering one week of guava, and fruit expanding period foliage-spray three times, spray interval time is 13 days at every turn, is namely rich in selenium element after guava maturation.
