Description
Technical Field
The invention relates to the technical field of planting of Or citrus, and particularly relates to a selenium-rich Or citrus planting method.
Background
The important physiological function of selenium to human body is more and more paid attention to scientists of various countries, and the recommended intake of selenium nutrition is set by the countries according to the conditions of the countries. The us recommends daily intakes of selenium (RDI) of 70 and 55 micrograms/day for adult healthy men and women, respectively, and 75 and 60 micrograms/day in the uk. The intake of adults recommended by the Chinese academy of nutrition is 50-250 micrograms/day.
Selenium is mainly obtained from the daily diet of a human body, and therefore, the content of selenium in food directly affects the daily selenium intake of people. The selenium content of food is greatly influenced by geography, and the difference of the selenium content of soil causes great difference of the selenium content in foods in various places. The soil with selenium content below 0.6 mg/kg belongs to selenium-poor soil, and 72% of China's soil belongs to selenium-poor or selenium-deficient soil. The selenium content of the food in the areas is generally between 0.01 and 0.06 mg/kg, and the selenium content of the food is lower than 0.02 mg/kg, so the food is regarded as serious selenium-deficiency food, and the disease of selenium deficiency can be caused by long-term intake of the serious selenium-deficiency food. Guangxi is a "selenium-rich county", and the soil selenium-containing area is the first to live across the country. According to the stipulation of the classification requirement of selenium content of selenium-rich agricultural products, the selenium content in each kilogram of vegetables and fruits can reach 0.01 to 0.1 milligram, and the vegetables and fruits can be called as the selenium-rich agricultural products.
The Or (Orah) is a perennial evergreen fruit tree of Citrus (Citrus) of Rutaceae, is a hybrid of "tanpul" orange and "Danxi" red orange, and belongs to the type of Citrus reticulata. The hybrid citrus unshiu has the characteristics of strong tree vigor, beautiful fruit appearance, excellent quality, late maturity, early fruiting and high yield, long fruit harvesting period, wide adaptability, strong disease resistance and the like, and is suitable for being popularized as a late-maturing hybrid citrus variety. 13.3% of soluble solid in the Or, 0.58% of titratable acid, 12.76 g/100 ml of invert sugar, 6.84 g/100 ml of reducing sugar, 23.69 mg/100 ml of Vc content and 22.9 of solid-acid ratio. The edible rate is 74.62%, and the juice yield is 59.56%.
The quality of the current selenium-rich Or citrus products is uneven, and the actual selenium content in most products can not meet the standard requirement at all.
Disclosure of Invention
The invention provides a planting method of rich-selenium Or citrus, aiming at the technical problems, which can improve the yield of Or citrus and improve the selenium content in Orangent citrus pulp.
In order to achieve the purpose, the invention adopts the following technical scheme:
a selenium-rich Or citrus planting method comprises the following steps:
(1) spraying a foliar fertilizer A containing paclobutrazol and monopotassium phosphate in the flower bud differentiation period;
(2) spraying a foliar fertilizer B containing cytokinin and medium and trace elements from the time before blooming to the bud period of spring shoots;
(3) spraying boron, phosphorus and potassium-containing foliar fertilizer C in the bud period; when the flowers are withered 2/3, spraying leaf fertilizer D containing gibberellic acid or gibberellic acid, brassinolide;
(4) spraying selenium, iron and vitamin E-containing foliar fertilizer E before the color of the fruiting trees in the young fruit period avoids rainy days; and spraying calcium-magnesium foliar fertilizer F in the young fruit period and the color transition period.
Further, in the step (1), the preparation method of the foliar fertilizer A comprises the following steps: diluting 25% paclobutrazol by 400-500 times, diluting monopotassium phosphate by 500 times, and mixing the two to obtain the paclobutrazol-potassium phosphate mixed powder.
Further, in the step (1), the spraying frequency of the foliar fertilizer A is 1-2 times.
Further, in the step (2), the cytokinin in the foliar fertilizer B is benzylaminopurine with the mass percentage of 1-3%; the trace elements comprise 10-20% of boron, zinc, iron and molybdenum in percentage by mass.
Further, in the step (2), the spraying frequency of the foliar fertilizer B is 2 times, and the spraying frequency is once every 15 days.
Further, in the step (3), the mass percentage of boron, phosphorus and potassium in the foliar fertilizer C is 10-20%.
Further, in the step (3), the preparation method of the foliar fertilizer D comprises the following steps: adding 50-75 kg of water into 1g of 75% gibberellic acid crystal powder to obtain the gibberellic acid crystal powder; or adding 600 kg of water into 250 ml of 3% gibberellic acid, diluting 2000-3000 times of 0.01% brassinolide, and mixing with 10-15% of boron fertilizer in percentage by mass to obtain the boron fertilizer.
Further, in the step (3), the spraying frequency of the foliar fertilizer D is 2 times, and the spraying frequency is once every 20-30 days.
Further, in the step (4), in the foliar fertilizer E, the mass percent of selenium is 0.005-0.015%, the mass percent of iron is 5-10%, and the content of vitamin E is 0.1-0.3 g/kg.
Further, in the step (4), the preparation method of the foliar fertilizer F comprises the following steps: diluting 10% of calcium and magnesium elements by 800-1000 times to obtain the calcium magnesium phosphate.
Further, in the step (4), the spraying frequency of the foliar fertilizer E is 3 times, and the spraying frequency is 1 time every 10-60 days.
All percentage contents are in mass percent herein.
Compared with the prior art, the invention has the beneficial effects that:
1. according to the invention, through researching the nutritional requirements of the fertile oranges in different periods, the foliar fertilizer is correspondingly sprayed, and the extra-root topdressing is respectively carried out on the fertile oranges in the flower bud differentiation period, the period from before blooming to the spring tip flower bud period, the period before the color change of the young fruit period of the fruiting tree and the color change period, so that the scientific and reasonable sectional control is realized, and the cushion can be laid for the fertile oranges with better enrichment and selenium fertilizer absorption. The invention can supplement calcium for young fruits to prevent fruit cracking, and supplement calcium and magnesium in the color-changing period to facilitate color changing, maintain the hardness of the fruits, increase the sweetness and crispness and the like; and selenium fertilizer is sprayed in the young fruit period of the bearing fruit tree and is sprayed for all times before color change, so that the characteristic that the nutrition is absorbed most vigorously in the fruit swelling period in the young fruit period is utilized, selenium element can be promoted to enter pulp through fruit peel to the maximum extent, a selenium-rich Wo citrus product with relatively high selenium content is obtained, and the Wo citrus yield is improved.
2. Selenium, iron and vitamin E are added into the foliar fertilizer E, the iron content in the tree body is low, the iron exists in a high molecular compound, and the iron is not easy to transfer in the fruit tree body; it can promote the respiration of fruit tree and accelerate physiological oxidation, and is the activator of several enzymes, and the activity of the enzymes has very important action for absorbing nutrient, so that the iron element can promote the enrichment of selenium. The presence of vitamin E can reduce selenium consumption by Or, and increase selenium storage in Or. When iron and vitamin E exist simultaneously, the enzyme activity can be influenced in two directions of promoting absorption and reducing consumption, so that the enrichment capacity of the Or on selenium is synergistically improved.
