example

[0024] Example: sow seedlings in the open field from late March to early April, do a good job in field management, cultivate strong leek roots (1), determine the time for transplanting, remove the shoots before transplanting, and the height of the stubble should be high, generally 6-10cm (2 ), then dig out the leeks, and cut off 1 / 2 to 2 / 3 of the root system (3).

[0025] According to the volume ratio of the various materials listed in the following formula 1, mix them and stir evenly (4), then add water and stir, (5), when the relative water content of the matrix reaches about 80%, seal and ferment with a plastic film to 55-60 °C (harmless treatment), keep it for 7-10 days (6), after that, fill the cultivation tray with the substrate, and fill the cultivation pot with half a pot (7). Plant 4 to 6 leeks in the hole, plant them in concentric circles in the cultivation pot, plant a small poke in the center, about 25 plants, plant two circles around, and fill the substrate betwee...

Abstract

The invention relates to the leek disk-pot type cultivation method in greenhouse with organic substrate. The substrate formula using this cultivation method : cattle manure : rice husk : chicken manure : field soil=4:2:1:1 (volume ration). The cultivation disk is generally 37.5-45.5cm long (internal diameter length 36-44cm), 27.5-33cm wide (internal width 26-31.5cm), 8-12cm deep; the diameter of the upper mouth of the cultivation pot is generally 25-30cm, the diameter of the bottom is 17-20cm, the height is 20-25cm. The annual leek stools are transplanted into the cultivation disk or cultivation pot, and moved into sunlight greenhouse in the last ten days of September to the last ten days of November, the cultivation substrate is prepared according to the formula mentioned above, the density of plants is: in the cultivation disk, the bunch distance is 4.5-5.5cm and the seedling number per bunch is 4-6 plants, the leek planted in the cultivation pot appear concentric circles shape, the seedling number per unit area is same to that in the cultivation disk. It is easy to obtain the materials according to the cultivation method, and the method has the merits of low cost, high content of organic matter, good leek products quality and high edible safety.

Description

(1) Technical field [0001] The invention belongs to the technical field of organic matrix cultivation of horticultural plants. (2) Background technology [0002] The use of organic substrate cultivation technology can effectively overcome the continuous cropping obstacles such as soil flooding and serious soil-borne diseases in the cultivation of vegetables and flowers in protected areas; ) to grow vegetables; organic substrate cultivation technology overcomes the shortcomings of traditional nutrient liquid soilless cultivation technology, such as high difficulty and high input cost, and the products are not easy to meet the requirements of green food production. It is in line with my country's national conditions and has developed rapidly. [0003] The traditional soil cultivation of chives has serious insect pests such as chives and maggots, the application of quick-acting chemical fertilizers is large, the product is seriously polluted by pesticides, and the content of nit...
