Selenium-enriching and quality-improving cultivation method for carrots

Abstract

The invention discloses a selenium-enriching and quality-improving cultivation method for carrots. The method comprises the following steps: S1, seed selection: selecting carrot seeds without diseases; S2, planting field selection: selecting a field which is loose in soil texture, rich in organic matters and has a soil pH value of 5.5-7.8; S3, selenium-rich fertilizer preparation: feeding livestock with selenium-rich feed, and storing excrement and urine dung produced by the livestock after classified collection and processing treatment; S4, soil preparation and fertilization: before sowing, deeply ploughing soil of the carrot planting field, and scattering processed excrement into the soil; S5, timely sowing; S6, water management: using a water source doped with the urine in the S3 for irrigation; S7, topdressing and weeding: conducting topdressing and weeding regularly; S8, disease and pest control: adopting a plant protection policy of 'prevention first and comprehensive control'; and S9, harvesting. The selenium content of the carrots is effectively increased, the yield of the planted carrots is effectively increased, and meanwhile the carrots are good in taste, rich in nutrient value and good in quality.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a selenium-enriched and quality-enhancing cultivation method for carrots. Background technique [0002] Carrot is a variety of wild carrot in the genus Carrot, Umbelliferae, an annual or biennial herb. The root is strong, long conical, orange-red or yellow; the stem is erect, up to 90 cm high, much branched; the leaves are long-stalked, pinnately compound, the lobes are linear or lanceolate, and the apex is sharp; the base of the petiole expands, forming Leaf sheaths; compound umbels; peduncles with hispid hairs; numerous involucral bracts, leaf-shaped, and the outer edge of the umbrella in the fruiting stage is curved inward; flowers are usually white, sometimes with light red; flower stalks are unequal; roots It is eaten as a vegetable and contains various vitamins A, B, C and carotene.

Problems solved by technology

[0003] Selenium is an essential trace element for the human body. It has the functions of scavenging free radicals, anti-tumor, anti-oxidation, prolonging life and improving human immunity. Because of the important role of selenium, selenium-enriched products are widely used in planting. Selenium-enriched carrots are more common Carrots are relatively good in terms of taste, water content, nutritional value, and quality. However, in existing cultivation techniques, selenium-enriched carrots have low selenium-enriched content and low cultivation yield, which in turn leads to low carrot yield and poor quality.
