Problems solved by technology

It is also a raw material for making jelly (also known as ice powder), and has cosmetic value. The existing technology cannot know the impact of the amount of nitrogen fertilization on Daqiansheng, so it is impossible to control the optimal nitrogen fertilization amount of Daqiansheng, resulting in Daqiansheng. normal growth, for this reason, we propose a research method for the effect of nitrogen fertilization on the growth of Daqian

Embodiment 1

[0023] Carry out comprehensive site preparation before planting, dig the soil 30cm deep, and remove weeds and grass roots; the distance between rows and plants is 25cm, and before planting, it is necessary to break up soil blocks to make ridges, and the distance between ridges is 25cm. At the same time, triangular holes must be opened. At the beginning of the double row, the first plant hole is opened 12.5 cm behind the single row, and the distance between the plants is still 25 cm, so that the plant holes of each row are between the front and rear plant holes of the adjacent row, forming a triangle staggered to facilitate the growth of the plants. light, to obtain high yield; sow about 10 grains in each hole, cover with 1 cm thin soil after sowing, and water once permeable. After emergence, water frequently in the morning and evening to remove weeds in the field in time. Remove the holes and leave 2 strong seedlings, the seedling height is about 13 cm, and the seedlings are fi...

Abstract

The invention discloses a research method for the impact imposed on nicandra physalodes by the nitrogen fertilizer application amount, which comprises comparative analysis, wherein the comparative analysis for the impact imposed on the growth and development of nicandra physalodes by different application amount of a nitrogen fertilizer includes analysis for the impact imposed on growth charactersof nicandra physalodes by different application amounts of the nitrogen fertilizer, analysis for the impact imposed on production characters of nicandra physalodes by different application amounts ofthe nitrogen fertilizer and analysis for the impact imposed on the flavonoid content of nicandra physalodes by different application amounts of the nitrogen fertilizer. The research result shows thatthe nitrogen fertilizer has great impact on the plant height, the branch height, the leaf area and the plant yield of nicandra physalodes based on the above analysis, the reasonable application concentration range is 5-11kg / mu, and the optimum application concentration is 8kg / mu. The research method solves a problem that nicandra physalodes cannot grow normally because there is no way to know theimpact imposed on nicandra physalodes by the nitrogen fertilizer application amount the prior art and the optimum nitrogen fertilizer application amount of nicandra physalodes cannot be controlled.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a research method for the influence of nitrogen fertilizer application amount on plant growth. Background technique [0002] Nicandra physalodes (Nicandra physalodes) is a plant of the genus Pseudophysalodes in the Solanaceae family. It is native to Peru and is also known as Nicandra physalodes and Tianzhu. Born in fields, wastelands, fences, and around gardens, it is used for medicinal or ornamental cultivation in the north and south of my country. The whole plant has the effects of calming, eliminating phlegm, clearing away heat, detoxifying, and relieving cough, and can treat mental illness, rabies, colds, and rheumatism. , scabies embolism. The seeds have the effects of clearing heat and annealing, diuretic, expelling wind, and anti-inflammatory, and can treat fever, rheumatoid arthritis, sore carbuncle, swelling and pain. The flowers have the functions of expellin...
