Description
Technical Field
The invention relates to the field of industrial hemp planting.
Background
In the process of planting management of industrial hemp, the number of male plants is increased under the influence of illumination, nitrogen fertilizer usage and air temperature, and after the number of male plants is increased, if the male plants bloom early and are asynchronous with the female plants, pollination of the female plants is also affected, formed seeds are not full, and after the male plants bloom, the plants can finish growing in a short time, enter a withering period, do not form useful value, waste planting cost, reduce extraction amount of CBD and direct economic benefit.
Disclosure of Invention
The invention provides a seed setting transformation method for an industrial male marihuana plant, aiming at solving the technical problems that the pollination of female plants is influenced and the formed seeds are not full due to early flowering of the existing male plants.
The industrial marihuana male plant seed setting conversion method comprises the following steps:
firstly, when the length of the flower spike of the industrial hemp reaches 10cm, cutting off the flower spike; then, spraying iodine tincture on the leaf surfaces;
secondly, after two days of treatment in the first step, irrigating by using a mixed solution of chitin, a seaweed rooting fertilizer, potassium dihydrogen phosphate and water, loosening soil after one day, keeping illumination, and controlling the temperature to be 15-26 ℃ and the humidity to be 80-82%;
and thirdly, spraying the mixed liquid of chitin, monopotassium phosphate, boron fertilizer, zinc fertilizer, leaf fertilizer and water on the leaf surface every five days after the treatment of the second step, and culturing until the plant blooms and seeds, thereby completing the method.
The industrial hemp plants can bloom when the height of the plants is 50 cm and the diameter of the plants is 0.5 cm, bunch buds grow like bananas and do not bloom, two layers of leaves are left on the ground in the morning of a sunny day, and flower ears are cut off.
After the spica is cut off, iodine tincture is sprayed on the leaf surface to seal the wound and prevent bacterial infection from the wound.
The invention has the beneficial effects that:
the method changes the nutrient supply way by cutting off the spica, changes the content of nitrogen, phosphorus and potassium in the fertilizer, thereby changing the sex of industrial hemp, wherein the chitin in the fertilizer has broad-spectrum antibacterial property, induces crops to generate various resistant substances, is beneficial to healing the cut-ear wound and can promote the growth of the root system; the seaweed rooting fertilizer can make plants root quickly, promote the tip of the root system to grow, and increase the fertilizer absorbing capacity of the root system; the potassium dihydrogen phosphate can promote the growth of plant roots; the boric fertilizer can promote flower bud differentiation; meanwhile, the illumination duration is controlled, so that the growth of the plant root system is facilitated; when the main root of the hemp plant is developed and the capillary root of the lateral root is in a various state, the male plant is changed into the female plant, through verification, the planting management according to the method of the invention has the phenomena of cauchy fork after ten days, more than ten branches are differentiated after 20 days, and then the flowers bloom successively and full seeds are formed, thus being capable of preparing for the seed source of the next year. Therefore, when the flower spikes are cut off, the components of the fertilizer are reasonably regulated and controlled to be irrigated and sprayed, the sex of the industrial hemp is changed, the service life of the industrial hemp is prolonged, the economic value of male plants is improved, and the cost investment is reduced, so that the method has important significance for the planting of the industrial hemp. The male plant seed setting conversion rate reaches 90%, the CBD yield is improved, the effect of the male plant is fully exerted, the economic benefit is increased, and the effects of increasing the production and income are achieved.
The method is used for industrial marihuana male plant seed setting.
