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 potassium fertilization on Daqiansheng, so it cannot control the optimal amount of potassium fertilizer for Daqiansheng, resulting in Daqiansheng. normal growth, for this reason, we propose a research method for the effect of potash fertilizer application 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 method for studying the influences of the application rate of a potassium fertilizer on Nicandra physalodes. Comparative analysis of the influences of different fertilizer application rates on the growth and development of Nicandra physalodes includes analysis of the influence of different application rates of potassium chloride on the growth characters of Nicandra physalodes, analysis of the influence of different application rates of potassium chloride on the yield trait of Nicandra physalodes and analysis of the influence of different application rates of potassiumchloride on the flavone content of Nicandra physalodes. A result of the above comprehensive analysis shows that the potassium fertilizer has great influences on the stem diameter, the branch stem diameter and the flavone content of Nicandra physalodes, and the reasonable application rate is in a range of 8-15 kg / 666.7 m<2>. The reasonable application rate of the potassium fertilizer, being 8-15 kg / 666.7 m<2>, is obtained through comparative experiments, so the fertilization amount of Nicandra physalodes is standardized, and the yield and the flavone content of plants are increased, thereby the problem of the influences of nonstandard fertilization of the Nicandra physalodes in existing cultivation technologies on the metal pollution treatment of the Nicandra physalodes and the preparationof novel biological pesticides is solved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a research method for the influence of potash 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 and other diseases. 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 ...
