Abstract

The invention discloses a nutrient solution based on substrate cultivation of saffron and a cultivation method thereof.The nutrient solution comprises a solution A, a solution B, a growth regulator and a PH regulator, and the cultivation method comprises the steps that S1, vermiculite, straw, turf, dried pomace and coconut shell fiber are taken to be mixed and fermented to form a cultivation substrate; s2, a layer of plastic film is laid in a pre-formed groove, and the fermented culture medium is laid on the plastic film; s3, the solution A, the solution B and a growth regulator are prepared according to the proportion, then PH is adjusted, and the nutrient solution is prepared; s4, irrigating the stigma croci with nutrient solution and tap water in a micro-spraying dropper mode. The method has the advantages of being low in investment, easy to operate, low in cost, fertilizer-saving, water-saving, labor-saving and capable of achieving high quality and high yield of products.

Description

technical field [0001] The invention relates to the technical field of saffron cultivation, in particular to a nutrient solution based on substrate cultivation of saffron and a cultivation method thereof. Background technique [0002] Saffron, also known as saffron and saffron, is a perennial herb of the genus Crocus of the family Iridaceae. [0003] Saffron is native to Iran, India and other countries. The planting of saffron in my country began in the early 1980s and has a history of nearly 40 years of cultivation. Because the chromosome of saffron is triploid, the pollen abortion is high, and it is rarely fruity after flowering, and can only be propagated by bulbs. The reproduction rate of saffron bulbs is very low, the general ratio is only 1:1.2-1.5, so the reproduction rate is slow. In recent years, the proportion of saffron bulbs rot and yellow buds has continued to increase. Some data show that the rotten rate of saffron bulbs in general years is about 5%, and the ...
