Cutting method of chaenomeles cathayensis or chaenomeles speciosa

Abstract

The invention belongs to the technical field of plant cultivation, and particularly relates to a cutting method of chaenomeles cathayensis or chaenomeles speciosa. The annual or biennial strong branches of the chaenomeles cathayensis and the chaenomeles speciosa are taken as cutting slips; the lengths of the cutting slips are 5-10cm in general; the number of buds on the cutting slips is not less than 2; the cutting slips are sterilized for 2 hours by eluent prepared from alcohol of which the concentration is 3% before being cut; the cutting matrix is perlite; a cutting pool needs to be sterilized before cutting; the perlite needs to be sterilized before cutting; the cutting matrix is sprayed with water in a cutting process and respectively soaked for 1 hour or 0.5 hour in a solution of NAA100ppm or 200ppm; the depths of the cutting slips in the soil probably are 1 / 3 of ear lengths and do not exceed 1 / 2; the row distance of the cutting slips is 5*5cm; the matrix is kept humid after cutting, and sprayed at fixed time, and an intermittent spray facility is used to spray the matrix for 30 seconds at an interval of 15 minutes to keep certain humidity. A cutting bed and the matrix are sterilized at the fixed period after cutting, and the temperature is more than 15 DEG C in the cutting process.
