Vacuum vegetables are extremely viable, adaptable, hot and wet, growing at about 30°c, resistant to high temperatures above 35°c, intolerant to cold, slow to grow at temperatures below 10°c, and can be sowed several times at a time, and combined with protected site facilities to grow to meet the anniversary supply. The introduction of organic eco-planting techniques, the implementation of cleaner production, the application of organic fertilizers, the reduction of pesticide use, the improvement of the vegetable growth environment, the removal of barriers to soil connection, and the savings in production costs, as well as the rapid growth of vegetables, high yields, good product quality and non-hazardous vegetables, are popular in marketing and are in line with current requirements for ecological agricultural development。
1 establishment of organic eco-planting systems
1. 1 construction of planting tanks
25-30cm tall, 50cm wide, 70cm away, north and south, north and south. Brick sews can be glued to concrete solution and can also be filled with soil (one layer of old thin membrane under the sink)。
1. 2. Cultivation matrix
Mushroom slags, slags are mixed at 1:1 ~1. 5, 1 m3 mixed matrix is added to 10 kg of sterile inflatable chicken dung, and 2kg of triple compound fertilizer. Where possible, fine sand, grass-breed, stork, organic fertilizer may also be combined into a composite matrix at a ratio of 2 = 1:1:2 and organic fertilizer may be good with chicken and sheep dung。
1. 3 slots
Paint sand in the sink, about 5 cm thick. Load a mixed matrix into a ready tank, flatten it and pour it through. When the water is fully immersed, the film is then covered with 10-15 d to be fully decomposed by the fertilizer。
2 seeding and breeding
2. 1 leaching seedling
Before seeding, 30min is immersed in 50-60°c hot water and 24h in clean water. Leaching is followed by washing and seeding at 30°c. During the sprouts, the seeds can be sowed with hot water once a day, after approximately 5-7d。
2. 2 leapboards and matrix preparation
Vaccination plate specifications for hollow vegetable seedlings are generally selected for 72 or 128 holes. It is advisable to use light matrices such as grass-grass, neptunite or pearl rock, which are small in weight and have a good permeability. For seedlings with light substrates, the base formulation ratio is typically grass charcoal: neptunium: corroded organic fertilizer = 2. 1:1. The matrix must be insecticidal in order to breed disease-free seedlings. In general, the 1 m3 matrix uses 50 per cent of the polybacterial water powder and 150 g of thiophos-methyl cream。
2. 3 baseware and seeding
The seeding shall begin with the planting of seedlings, which shall be packed in the lair, and the excess matrix shall be scraped; the matrix shall be filled with water, which shall be covered with an empty plate of 2 to 3 of the same specifications, and the seeding den shall be crushed. The seeding covered a layer of leeches and covered the wetting with film. After seedlings are released, the cover is removed in time for the wind to shine。
2. 4 slender bed management
The temperature is around 25°c during the day and above 10°c at night. Water management is the key to the success or failure of seedlings, and it should be ensured that the seedling base remains humid throughout the period. At heights of 5-7 cm, a leaf fertilizer is sprayed with a common concentration of 0. 2% urea or potassium phosphate. It will be ready to grow as long as 10-15 cm。
It's three
The range of the empty cabbage is about 15 cm x 15 cm. Setting time, usually in the afternoon. Before planting, water from the bottom is poured, and when water is mixed, seedlings are implanted in the matrix, where appropriate, and buried deep in 2-3 knots. The foundational cultivation is almost unsettled and will soon enter normal growth。
4 field administration
4. 1 fertilizer water management
When the hollow dish is set, it can be collected repeatedly. On cultivation, a high yield can be achieved only by the application of base fat and the timely pursuit of fat after each harvest. Catch urea 2
4kg. Empty cabbage is wet and requires a large quantity of water and should be watered on a regular basis to remain wet at all times. In general, during the harvest period, water is poured every 4-5d, and so on。
4. 2 pest management
Organic eco-friendly soilless cultivation, with small varnish pests. The main ones are sprawl, stasis, rusty, white lice, snails, larvae, red spiders, locusts, aphids, soy moths, etc. In my city and surrounding areas, snails and larvae are the worst affected. Insect nets are commonly used to prevent pest transmission and reduce the use of medicines。
5 collections
A one-time harvest of hollow dishes can be taken to the market at 25-30 cm. In the case of multiple harvests, the first can be taken at 30 cm high, with two spas in the base; the second can be taken under section 2 left by the base; and the third can be taken under the first truncheon left by the base, in order to stimulate new buds。
In the event of a weakening of hollow cabbage, the base is replaced, the base fertilizer is applied, and the seedlings are quickly breeded using top plugs. Around 15d, you can re-listed。
