A kind of cultivation method of macadamia nut seeds

Abstract

The invention relates to the technical field of macadamia seedling cultivation; in particular, it relates to a method for cultivating macadamia seeds, aiming at shortening seed germination and emergence time, reducing seed treatment costs and harmful effects, improving seed adaptability, grafting survival rate, improving emergence rate and The uniformity of seedlings adopts the following method: including the following steps: (1) fruit selection and grading; (2) mixing: seeds are mixed with phosphogypsum; (3) one-time soaking: seeds are placed in the trigger film liquid, exposed to sunlight or Soaking under simulated sunlight conditions; (4) exposure: expose the fished seeds to sunlight or simulated sunlight conditions until the shells crack; (5) secondary soaking: put the cracked seeds in the microbial extract Soaking at constant temperature; (6) Sowing: Sowing the seeds on the seedbed; (7) Transplanting: Transplant the seedlings into the nutrition bag for cultivation until the seedlings are 25‑30 cm long and the stems are more than 0.5 cm thick. rootstock.

Description

technical field [0001] The invention relates to the technical field of macadamia seedling cultivation; in particular, it relates to a method for cultivating macadamia nut seeds. Background technique [0002] Macadamia nuts belong to the genus Macadamia of the family Scutellaria, also known as Queensland nuts, macadamia walnuts, and poppy nuts. Or milky white, rich in nutrition, oil content of about 70%, protein 9%, containing 8 kinds of amino acids necessary for the human body, also rich in minerals and vitamins B1 and B2, crispy and delicious, with a unique buttery fragrance, excellent taste and flavor, In addition to making dried fruit, it can also make high-grade pastry, chocolate, cooking oil, cosmetics, etc. [0003] Macadamia nut seedling cultivation methods include cutting seedlings, grafting seedlings, and plant tissue culture seedlings; plant tissue culture is limited by the large investment in early equipment, high operating requirements, and difficulty in rooting...

Problems solved by technology

Patent No. CN201710187445.9 discloses that the seeds are first sterilized with mercuric chloride solution, then alcohol, and then frozen at -20 to -18°C for 15 to 30 days, and the frozen seeds are placed at 4°C for 5 to 10 days. God, although it helps to increase the thickness of the stems that the seeds germinate and grow into rootstocks, it is easy to cause mercury poisoning and does not meet the safety concept

[0005] In addition, the patent number CN20171089967.3 discloses the steps of soaking seeds with medicinal liquid. This technical solution mainly uses yellow light, red light and purple light to carry out intermittent mutagenesis treatment on seeds, thereby shortening the time for seed germination, but it is difficult to improve the neatness of seedlings. Degree and anti-irritation ability

Patent No. 20091009458.0 discloses that "choose the mature fruit of the macadamia mother tree, peel off the outer green peel, soak it with 0.3-0.5% carbendazim or methylbutazine aqueous solution for 2-3 days, and then expose it to the sun until Hard nut shells are cracked", but this technical solution mostly uses commercially available disinfection reagents and growth regulators, which not only increases the cost, but also easily leads to toxic residues, and it is difficult to improve the emergence period of this solution

Patent No. 20171089968.7 discloses "Preparation of seedbeds: select sandy land, plow deeply, and spray Chinese medicinal liquid. The traditional Chinese medicinal liquid consists of the following raw materials by weight: 3-5 parts of Daqingye, 1-2 parts of Asarum, 2-4 parts of white cardamom powder, 2-3 parts of capillary, 2-3 parts of desmodium, 1-2 parts of Viola chinensis, 2-4 parts of dandelion and 800 parts of water are mixed and decocted for 2-3 hours; then Applying 40-50 kg / m2 of self-made organic fertilizer, said self-made organic fertilizer includes the following components in parts by weight: 100-150 parts of decomposed cow dung, 60-80 parts of decomposed vermicompost, 40-50 parts of A. 20-30 parts of pomegranate, 10-20 parts of lobelia, 10-15 parts of light bamboo leaves, 10-12 parts of potassium ore powder, and 2-4 parts of organic bacterial agent; spray the traditional Chinese medicine liquid for the second time, and then do it on the ground However, this plan uses many traditional Chinese medicines, and also uses a large amount of snail liquid, honey, selenium-enriched amino acids, bamboo vinegar, etc., not only the source is not easy, but also because the production time of each material is inconsistent, so it is difficult to simultaneously Obtained and need to adopt other means for effective preservation, which increases the cost and workload

[0006] At present, macadamia nut seeds take a long time to emerge, and the uniformity of emergence is poor, which is not conducive to subsequent grafting. At the same time, the distribution of roots is shallow and the main root is not obvious, which seriously affects the survival rate of grafting. Therefore, there is an urgent need for a fast, neat emergence, low cost, green Environmentally Friendly Seed Breeding Methods
