Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a method for breeding pineapple seeds with ventilation and water retention. The sponge of the present invention is used as a breeding substrate for pineapple seeds, which can effectively solve the problem of hardening of paper due to lack of water, long-time soaking of seeds, mildew and rotting of roots and The root system is entangled with each other and completely attached to the paper sheet, which is not easy to transplant seedlings. At the same time, nutrient solution is added during the seedling cultivation process to replenish the nutrients required for seedling cultivation in time, so that the root hairs of seedlings are loose and water-retaining, and the root system is developed, which shortens the breeding time of seeds and improves the quality of seeds. Germination rate, seedling survival rate, and the cultivated pineapple seedlings are not easy to damage and break roots when transplanting.

Embodiment 1

[0041] Pineapple seed germination comparison experiment:

[0042] (1) Seed washing: The fresh seeds collected are wrapped with cotton gauze, and the transparent seed coat attached to the seed coat is thoroughly cleaned by rubbing repeatedly. While cleaning, pick and remove the incomplete and damaged seeds. seeds, spare;

[0043](2) Seed soaking and sterilization: wrap it with a single layer of cotton gauze, put it in the prepared sterilizing solution for 15-24 hours, take out the whole package of seeds after the disinfection is completed, and rinse them with sterile water for 3-5 times, and then keep the seeds intact. Place it in a clean container, and add sterile water to ensure that the seeds are moist and ready for germination.

[0044] (3) Germination: 3mm medium-density sponge, 5mm high-density sponge and filter paper were respectively put into petri dishes for experiment, with 100 seeds in each group.

[0045] Group A, traditional filter paper culture group.

[0046] ...

Embodiment 2

[0053] Pineapple seed seedling comparison experiment:

[0054] (1) Nursing seedlings: Pick out the pineapple seeds germinated through the spongy sprouting break in the early stage, and put them into a new petri dish for seedling cultivation.

[0055] 3mm medium density sponge, 5mm high density sponge and filter paper were put into different petri dishes for experiments, 30 capsules in each group.

[0056] Add sterile water to the petri dish to moisten the sponge, cover the petri dish and mark it, and place it in an artificial climate box for seedlings. Gran's nutrient solution once, and 1ml of nutrient solution is added dropwise at intervals of 7 to 10 days. When the pineapple seedlings grow 4-7 mature leaves, they can be transplanted in time;

[0057] The composition of modified Hoagland's nutrient solution is: Ca(NO 3 ) 2 .4H 2 O 945mg / L, KNO 3 506mg / L, NH 4 NO 3 80mg / L, KH 2 PO 4 136mg / L, MgSO 4 241mg / L, FeNaEDTA 36.7mg / L, KI 0.83mg / L, H 3 BO 3 6.2mg / L, MnSO...

Embodiment 3

[0064] Contrastive experiment of root damage in transplanting seedlings with different seedling mediums

[0065] (1) seedling transplanting plug tray: gently peel off the pineapple seedlings from the seedlings of the different seedling mediums of Example 2, record the root system of the seedlings in Table 3, and then be planted in a nutritious soil filled with In the plug tray, it is advisable to slowly pour the foot-fixing water to the bottom of the plug tray with a little water seepage, and finally place it on the seedbed for daily maintenance.

[0066] The nutrient soil is a mixture of peat, coconut bran and perlite in a ratio of 3:2:1, in which the organic matter is greater than or equal to 90%, and the nitrogen, phosphorus and potassium is greater than or equal to 2.5%.

Abstract

The method comprises the following steps: firstly, cleaning fresh pineapple seeds, soaking and sterilizing, putting the pineapple seeds into a culture dish with sponge for accelerating germination, adding sterile water, and putting the pineapple seeds into an artificial climate box for accelerating germination; the method comprises the following steps: timely picking out broken and germinated pineapple seeds, putting the pineapple seeds into a new sponge culture dish, adding sterile water, putting the new sponge culture dish into an artificial climate box for seedling raising, adding a small amount of nutrient solution for multiple times according to the growth condition of seedlings, and transplanting the pineapple seedlings when the pineapple seedlings grow 4-7 mature leaves; and planting pineapple seedlings in a hole tray filled with nutrient soil, and placing the hole tray on a seedbed for daily maintenance. Sponge is adopted as a pineapple seed breeding matrix, the problems that paper is hard due to water shortage, seeds are mildewed and rotten due to long-time soaking and seedlings are not easy to transplant due to mutual winding of root systems and complete adhesion of paper in the pineapple seed breeding process through filter paper are effectively solved, seedling root hair is germinated through loosening and water retention, the root systems are developed, the seed breeding time is shortened, and the yield is increased. The germination rate of seeds and the survival rate of seedlings are improved, and the roots of cultivated pineapple seedlings are not prone to being damaged and broken during transplanting.

Description

technical field [0001] The invention belongs to the field of crop seedling raising, in particular to a method for breeding pineapple seeds. Background technique [0002] Pineapple belongs to the bromeliad family and is mainly grown in tropical and subtropical regions. Its output ranks third among tropical fruits after bananas and citrus, and it is also one of the most economically valuable fruits in the world. At present, it is cultivated on a large scale in Fujian, Guangdong, Hainan, Guangxi and Yunnan in China. [0003] Pineapple is rich in nutrients and contains almost all the vitamins needed by the human body, which can effectively help digestion and absorption. Pineapple can effectively acidify fat, clean up the stomach, and bromelain can effectively decompose protein in food, increase gastrointestinal motility, and at the same time taste sweet and sour, which is very popular among the public. It is eaten as fresh fruit, processed as canned food, and used as a flavori...
