Soilless cultivation techniques of Noodle vegetables on balcony

Planting vegetables and flowers on the balcony can not only decorate the room and beautify the environment, but also enrich family life, add special vegetables and eat cabbage, which can be regarded as a good measure to get more than one move. Balcony soilless cultivation of many kinds of vegetables and flowers, the choice of varieties to characteristic varieties and easy to cultivate mainly, the following balcony soilless cultivation of noodle vegetables to do the following introduction.

Noodle vegetables, a kind of wild vegetables, is one of the main weeds in wheat fields, commonly known as wheat bottle grass, Miwa can, Maiga, botanically belongs to the Caryophyllaceae, tender seedlings known as noodle vegetables, mainly steamed food, can also be fried, cold, soup, quite good flavor. Traditional Chinese medicine says that it has the effects of moistening the lungs and relieving cough, cooling blood and stopping bleeding, and can treat fatigue cough, nosebleed, hematemesis and other diseases. its growth environment is similar to that of wheat. it is a kind of low-temperature and long-day plant. Artificial cultivation mainly uses seedlings growing in the vegetative growth stage as products.

Prepare soilless matrix

There are many formulations of soilless matrix, which can be taken nearby. The commonly used formulations are:

1. The ∶ slag of peat soil is 4 ∶ 6. Peat soil can be purchased in the flower market, and cinder can be screened with honeycomb cinder.

two。 Mushroom residue ∶ corn straw ∶ vermiculite ∶ coarse sand is 3 ∶ 5 ∶ 1 ∶ 1. Corn stalks should be broken into small segments of 2 cm to 3 cm and soaked in water, and then fermented with other substrates. 10 kg of sterilized chicken manure and 1 kg of 1.5 kg diammonium phosphate and potassium sulfate were added to each cubic substrate during fermentation, and the fermentation days were not less than 20 days. turn the pile every 7 days.

3. Corn straw ∶ vermiculite ∶ mushroom residue is 3 ∶ 3 ∶ 4.

4. Slag ∶ mushroom residue ∶ sawdust is 3 ∶ 5 ∶ 2.

The technical index of soilless culture substrate requires that the proportion of organic matter is 50% ~ 60%, the ratio of carbon to nitrogen is 30, the pH value is 5.8-6.4, and the total nutrient is 33.5 kg / m2. The three elements of nitrogen, phosphorus and potassium are the main indexes.

Prepare cultivation equipment

Choose a larger diameter flowerpot or foam box and load it into a soilless matrix with a thickness of not less than 15 cm.

Sowing seeds

First of all, the soilless matrix was soaked with water to keep the water content of the matrix up to 60% ~ 8.5%. Then sow noodles and cover 1cm to 2cm substrate by sowing. It should be noted that the suitable temperature for noodle growth is slightly lower, generally at 15: 20 ℃, 20: 25 ℃ in daytime, no more than 25 ℃ in daytime, 10: 12 ℃ at night, and 5: 6 days after sowing. Generally summer is not suitable for sowing, the best sowing season is in late autumn and early winter, of course, indoor planting can be planted year-round by adjusting the temperature.

Administration and Management

Indoor cultivation of noodles, before and after emergence should be watered with small water or sprayed with a spray pot to keep the ground moist and prevent soil consolidation from affecting seedling emergence. At the same time, in order to promote seedling emergence and seedling quality, 2% urea solution can be added to the sprayed water, and the seedling growth effect is very obvious. Noodles have entered the vigorous growth period, because of high planting density and high water demand, they should be watered frequently to ensure adequate supply of fertilizer and water to facilitate stem and leaf growth. When the seedlings grow to 2 or 3 true leaves, the first topdressing should be carried out, and the nitrogen, phosphorus and potassium three-element compound fertilizer should be applied with the water, the dosage is 1.5 kg / m2, and the second topdressing should be carried out after 10 days.

Harvest

Indoor cultivation of noodle vegetables, about 40 days after emergence, grow 10-16 leaves, can be combined with sparse seedlings to harvest one after another, generally pick noodles with a knife. In order to increase the output and uniformity and prolong the supply period, it is appropriate to grasp the principle of large harvest and small harvest, careful harvest and frequent harvest, but need to be flexible. It can be harvested once every 15-20 days, and can be harvested 3-4 times.
