Planting method of selenium-rich pitaya

Abstract

The invention discloses a planting method of selenium-rich pitaya. The planting method is characterized by comprising steps as follows: land selection, seedling culture, field planting, pruning and trimming, nutrient and water management, orchard management and pest control. The planting method adopts advanced tillage, fertilizer and insecticide technology such as selenium-rich bio-organic fertilizer, selenium-rich organic-liquid active fertilizer, organic fertilizer, a smashing ridge machine and the like, so that soil environment is effectively improved, the content of organic matters and selenium in soil is greatly increased, the selenium content of the planted pitaya is high, the pitaya yield is high, the detection indicates that the selenium content of the pitaya is 0.40-0.50 mg / kg, furthermore, according to the insecticide technology adopting botanical insecticides and botanical fungicides, the better insecticidal efficacy is realized while nutrition is guaranteed, and the economic benefit is very obvious.

Description

technical field [0001] The invention relates to a cultivation method of economic crops, in particular to a cultivation method of selenium-enriched dragon fruit. Background technique [0002] pitaya (Hylocereus undulatus Britt.) Pitaya, also known as red dragon fruit, dragon fruit, xianmi fruit, and jade dragon fruit; it is the fruit of the genus Liangtianchi in the cactus family. It is native to Mexico and Brazil in Central and South America. It has been artificially cultivated for several years. century. The peel of dragon fruit is red, and the peel has red elongated scales, and the pulp is evenly distributed with sesame-like seeds. The color of the pulp is white, yellow, red, and both the fruit and the stem are edible. Every 100 grams of dragon fruit pulp contains 82.55 grams of water, 6.1 grams of carotene, 0.17 grams of crude fat, 0.81 grams of protein, 1.21 grams of crude fiber, 13.91 grams of carbohydrates, 59.65 calories of calories, 1.62 grams of dietary fiber, and...

Problems solved by technology

[0005] At present, in order to plant selenium-enriched dragon fruit, the method of foliar spraying inorganic selenium is adopted, and its shortcomings are very obvious. First, foliar spraying requires a relatively high content of selenium fertilizer, and high-concentration selenium fertilizer increases the cost of fertilizer use; secondly, because Foliar spraying, selenium fertilizers are easy to spill into the field, which causes a lot of waste of runoff water and soil in the field; again, it often leads to large residual amounts of inorganic selenium, and inorganic selenium has obvious toxic effects on the body, which is safe Low toxicity, can not be used in the production of organic selenium-enriched agricultural products
