Passion fruit hydroponic seedling raising method

Abstract

The invention discloses a passion fruit hydroponic seedling raising method which comprises the following steps: S1, soaking and disinfecting devices for seedling raising, including a floating cutting fixing block and a cultivation box; cutting slips are sheared, cuts of the cutting slips are at least disinfected, and the cutting slips are aired after disinfection; s2, a floating type cutting slip fixing block capable of floating or being fixed on water is taken, the floating type cutting slip fixing block is provided with at least one clamping structure, the cutting slips are pressed into the clamping structures and placed into a cultivation box, the temperature of a water culture solution is controlled to be 18-25 DEG C, the air humidity is controlled to be 70-80%, and a proper amount of root system growing points grow out when the cutting slips are inserted into the water. According to the method, rooting of passion fruit cutting slips can be rapidly promoted, and seedling breeding of passion fruits is accelerated.

Description

Technical field [0001] The present invention relates to the field of passion fruit planting technology, in particular a passion fruit water seedling cultivation method. Background [0002] Passion fruit (scientific name: Passiflora edulis Sims) is a herbaceous vine of the genus Passionflower in the family Passionflower family, which thrives in the jungles of valleys at altitudes of 180–1900 m. Native to the Antilles, it is widely cultivated in tropical and subtropical regions. The fruit can be eaten raw or used as vegetables and feed. The drug has an exciting and strong effect. The fruit is a juicy liquid, with the addition of calcium bicarbonate and sugar, which can be made into aromatic and delicious drinks, and can also be added to other beverages to improve the quality of drinks. Seed oil, which can be eaten and soap,paint-making, etc. Its flowers are large and beautiful and can be used as ornamental plants in gardens. It is a typical tropical and subtropical plant of the pas...

Problems solved by technology

At present, the cutting seedlings of passion fruit are generally cultivated in soil. The method is to directly insert the pruned branches of passion fruit into the soil or put them into a nutrition bag for rooting and seedling cultivation. The disadvantage is that the rooting is slow and the efficiency of seedling cultivation is low. It takes 4 to 6 months to complete. , the labor cost is high, and the environmental damage is serious in the production process

Although there are also some parts that carry out water cultivation, as the publication number is CN110367059A, the invention patent application "passion fruit hydroponic cutting seedling cultivation method" discloses: cut the passion fruit branches with 2-4 axillary buds, and then cut off the bottom 2-3 Leaves on each bud node, keep the leaves and axillary buds on the top 1-2 bud nodes, as passion fruit cuttings, cover the mouth of the beaker where the sterile nutrient solution is with gauze or hard paper, and the buds must be kept The method has the following disadvantages: (1) in the existing technology, it is necessary to take soil on the spot or burn plant ash to prepare the nutrient solution through disinfection, which is time-consuming and increases the cost and low efficiency. At the same time, the production of plant ash may also cause damage and pollution to the environment; (2) The production of passion fruit cuttings must be cut with 2-3 bud nodes, and then cut off the leaves on the lower 1-2 bud nodes, leaving the upper 1 The leaves and axillary buds on each bud node will waste the bud nodes and increase the process, increase the cost and reduce the efficiency; (3) Passion fruit cuttings need to be placed in glass containers such as conical flasks that have been fully sterilized and filled with culture fluid, and the cuttings The number of glassware is limited, and it takes up a lot of space. Each glassware needs to be equipped with a large amount of nutrient solution, which also increases the cost, time-consuming and reduces efficiency; (4) The whole process must be carried out in a sterile environment, that is, It means that seedlings can only be grown in the laboratory or in a small area, and its operability is not strong
