Description

A kind of industrial cultivation technology of Lamiaceae plant Pengpengxiang

technical field

The invention belongs to the technical field of plant cultivation, and relates to a design and method for industrialized cultivation of the perennial herbaceous plant Pengpengxiang of the Labiatae family.

Background technique

Plectranthustomentosa (Plectranthustomentosa) belongs to the family Lamiaceae and is a subshrub perennial herb. Much branched, the whole plant is covered with fine and dense white hairs. Fleshy leaves, hairy, opposite, green, ovoid, with serrated edges. It enjoys the reputation of "Pengpengxiang" because it emits a comfortable aroma after touching. Because of its strong and sweet fragrance, which resembles the fragrance of apples, it also enjoys the reputation of "apple fragrance". It has the value of food, medicine and health care. It has beautiful appearance, emerald green leaves, pleasant smell, and can purify the air. It is an excellent green plant suitable for homes, offices and other places.

Pangpengxiang likes loose and well-drained soil, and it is not resistant to water and humidity. If it is too wet, its roots will rot and kill. There are also few domestic literature reports on whether Pangpengxiang can grow for a long time under cultivation, and only the cutting rooting experiment of 20 days in the experimental stage. Therefore, this breeding method has made a contribution to the tolerance and adaptability of Pangpengxiang to the growth environment. new additions.

Hydroponics is a kind of plant factory cultivation. Hydroponics is still in its infancy in my country and is an important part of green technology. The method is clean and hygienic, pollution-free, water-saving, fertilizer-saving, labor-saving, and has the advantages of unlimited cultivation sites, so it is widely liked by people in the process of urban development. Some studies believe that industrialized hydroponic flowers mainly use biological mutagenesis technology to induce non-aquatic flower tissues to produce a tissue structure similar to that of aquatic flowers, so that the roots of flowers can be soaked in water for a long time without rotten roots. This device adopts a static hydroponic system filled with solid medium, which is of great significance to the long-term viewing of Pangpengxiang.

At present, there are only a few studies on the industrial cultivation technology of Pangpengxiang. There are only a few studies on the effect of different concentrations of auxin on promoting cutting rooting, and it is in the stage of experiments for dozens of days. There are almost no hydroponic facilities and methods that can be popularized and easy to care for Pengpengxiang. Scientific reference, at the same time, the quantitative comparison of various morphological indicators of Pengpengxiang under hydroponic conditions is also unprecedented. It can be seen that it is of great significance to use certain hydroponic facilities and methods to promote Pengpengxiang to the hydroponic flower market.

Contents of the invention

The purpose of the present invention is to fill the gap in the industrial cultivation of Pangpengxiang, and provide a hydroponic design and method with high survival rate, strong tolerance and high ornamental value.

Concrete implementation of the present invention:

Take the annual healthy tender stems of Pangpengxiang as cuttings, disinfect them with 75% alcohol to prevent the cuttings from mildew and rot, soak the base of the branches in 10g/L rooting powder solution for 15 minutes, and then immerse the cuttings in the prepared nutrient solution for rooting and water environment exercise. The cutting time can be carried out under the condition that the temperature is greater than 5 degrees Celsius. During the rooting period, pay attention to keeping the leaf buds at the base of the cuttings slightly in contact with the liquid surface, which is very conducive to the growth of the root system. After the root sprouts grow, insert them into the designed hydroponic landscape bottle for modeling and later growth. During the growth period, the nutrient solution can be added according to the water level. If the liquid is turbid due to accidental pollution, the nutrient solution should be replaced in time, and the root system of the plant should be rinsed with clean water.

Two months later, the Pangpengxiang cultivated by the method of the present invention is in good growth condition, with well-developed root system, strong sweet and pleasant fragrance, and has certain ornamental value.

The present invention has the advantage that the cultivation method of the present invention has low production cost and high ornamental value. Moreover, cuttings can be cut at any time at room temperature, which is helpful for the landscape modeling of Pengpengxiang. Therefore, it is a practical factory cultivation method with simple process and low cost.

detailed description

1. Treatment of cuttings When the plant grows to a certain height, take the annual healthy tender stems of Pangpengxiang as cuttings (the average length is 15.20cm), remove the excess leaves at the base, and disinfect with 75% alcohol for 15s, at 10g/L Soak the base of the branches in the rooting powder solution for 10 minutes, put the cuttings in shallow water for 2 days to keep them fresh and perform preliminary rooting.

2. The preparation of the nutrient solution is improved on the Japanese garden formula, and the concentration of 1/2 garden formula is selected, in which the N content is 8.67mmol/L, the P content is 0.67mmol/L, the K content is 4.0mmol/L, and the Ca content 2.0mmol/L, Mg content 1.0mmol/L, S content 1.0mmol/L, prepared with high temperature sterilized tap water.

3. Industrialized cultivation component design (IC) (1) The water level of the nutrient solution is about 1/3 of the height of the hydroponic container (13cm high and 9cm in diameter). (2) The application of the water-absorbing rope adopts the capillary phenomenon of the absorbent cotton in the literature report to automatically keep the plant roots in the planting basket moist. The root system will not rot. (4) The use of ceramsite soil to fix plants in the planting basket has better moisturizing and ventilation effects.

4. The matrix formula (CK) of the control group was planted with plant organic bean cake fertilizer: northeast peat: vermiculite: perlite: sterile pure coconut brick equal to 1:1:4:1:2 for cutting planting, and watered according to the soil condition water.

5. After two months, the Pangpengxiang planted by the method of the present invention is in good growth condition, healthy and beautiful.
