Embodiment 1

[0054] Example 1 A cultivation method of white asparagus rich in rutin

[0055] Step 1. Seedling cultivation

[0056] Select 'Shuofeng', 'Atlas' and other varieties suitable for white asparagus cultivation. In early January, plastic greenhouse nutrient pots are used to raise seedlings, and in mid-to-late April, strong seedlings with a plant height of 30-35 cm are selected for planting.

[0057] Step two, colonization

[0058]One week before planting, dig a planting ditch according to the topographical trend. The width of the ditch is 1 m, the depth is 0.5 m, and the distance between the sides of two adjacent ditch is 1 m. placed separately;

[0059] Mix the soil and fertilizer in the mature soil layer and backfill the bottom of the ditch; backfill the upper part of the planting ditch with the raw soil layer, and pour water into it;

[0060] The fertilizer is: a mixed fertilizer of decomposed organic fertilizer and ternary compound fertilizer;

[0061] The dosage of the fer...

Abstract

The invention provides a rutin-enriched white asparagus cultivation method and a special diffused light insulated heat radiation regulation and control film thereof. The method comprises the steps of planting and laminating, wherein the film refers to a diffused light insulated heat radiation regulation and control film; in the laminating step, when the daily air temperature is 15-25 DEG C, the daily mean temperature in the greenhouse is 33.2-34.8 DEG C, and the daily mean temperature on the soil layer which is 10cm below the earth's surface is 26.5-28.2 DEG C, and when the daily air temperature is 27-35 DEG C, the daily mean temperature in the greenhouse is 35.6-37.4 DEG C, and the daily mean temperature on the soil layer which is 10cm below the earth's surface is 32.7-33.5 DEG C; in the planting step, the line spacing in the planting furrow is 50cm, the line spacing between the furrows is 1.5m, the average line spacing is 1m, the row spacing is 25-28cm, and the planting density is 2380-2660 plants per mu. According to the produced white asparagus, the rutin content is 1300-1500mg / kg and is increased by 60-80 percent.

Description

technical field [0001] The invention relates to a method for cultivating asparagus, in particular to a method for cultivating white asparagus rich in rutin and a special light-scattering, heat-insulating and heat-radiation regulating film, belonging to the field of agricultural technology. Background technique [0002] asparagus( Asparagus officinalis L.) is a plant with both food and medicine, which has excellent pharmacological effects such as anti-fatigue, prevention and treatment of hypertension and heart disease, inhibition of tumor cell growth, and improvement of human immunity. The tender stems of asparagus contain more flavonoids, among which the content of rutin is significantly higher than other flavonoids, and its antioxidant capacity is stronger than that of vitamin C, vitamin E and carotenoids, especially the tip of asparagus , the rutin content is more than 5 times that of the stem base, and is called "gold in the dish". Rutin, also known as vitamin P, is a g...
