Method for cultivating seedlings by means of green branches under full exposure and light mist condition

Abstract

The invention belongs to the field of crop growing and particularly relates to a method for cultivating seedlings by means of green branches under the full exposure and light mist condition. According to the method for cultivating seedlings by means of green branches under the full exposure and light mist condition, seedling cultivation facilities are simple, investment is low, the influence on blooming, in the next year, of a female parent is small, plants which can grow under natural condition can be cultivated directly at a time, and the survival rate can reach 90%. The method for cultivating the seedlings by means of green branches under the full exposure and light mist condition comprises the following steps of (1) seedbed manufacturing, (2) branch selection and ear trimming, (3) hole forming and cuttage, (4) mist spraying control, (5) management after cuttage, and (6) seedling hardening, wherein according to mist spraying control, after cuttage, secondary sterilization is conducted, a high-pressure light mist control system is started at the same time, five billion mist particles are generated by a nozzle per second, the diameter of each mist particle ranges from 0.5 micron to 5 microns, and a water film exist on the surface of each leaf all the time under the full exposure condition; according to management after cuttage, sterilization is conducted in the day when cuttage is conducted, mist spraying is conducted every seven days since then, mist spraying is conducted every ten to fifteen days after the seedlings strike roots, mist spraying is stopped in the later stage, foliage dressing is conducted once every ten days, embryogenic calluses appear after seven to eight days generally, and a large amount of roots are generated after fourteen days.

Description

technical field [0001] The invention belongs to the field of crop cultivation, and in particular relates to a method for raising seedlings with full-illumination green branches and micro-fog. Background technique [0002] The propagation methods of roses include sowing, grafting, layering, ramets and cuttings. Damascus roses are different from traditional Chinese roses. They have no seeds and are not easy to cut. The existing technology is usually obtained by layering or conventional cuttings. seedlings. [0003] Cutting seedlings: cuttings are also called green branch cuttings. It uses semi-lignified green branches as cuttings for cutting and raising seedlings. Because of the high auxin content in the shoots, the tissue is young, the meristem is active, and the terminal buds and leaves have the effect of synthesizing auxin and rooting hormones, which can promote the production of Callus and rooting. [0004] The main points of the cutting technology at present are as fol...

Problems solved by technology

[0011] The method of cutting seedlings has the following disadvantages: first, the cuttings are directly inserted on the seedbed in the greenhouse, the spacing between the plants and the spacing is irregular, the speed is slow, the land occupation of the seedlings is unreasonable, the nutrition is unbalanced, and the survival rate is extremely low , even less than 20%

Second, when maintaining the water before the root system of the cuttings, it mainly depends on watering or sprinkler irrigation. Cuttings are dry or rotted and died due to excessive humidity

Third, the treatment of disinfection and rooting of cuttings is unscientific, mainly because the ratio of materials and plant growth regulators is unscientific, resulting in slow root development after cuttings, usually after 18 days before rooting

Thick substrate, not energy efficient
