What is noodle dish? How to carry out soilless cultivation of noodle vegetables? Noodle dish is a kind of wild vegetable, commonly known as Mecca. It can cure cramps, nosebleeds, vomiting blood and other diseases. Its growth environment is similar to that of wheat. It is a low-temperature long-day plant. The following is a description of the no-cultivation noodle dish on the balcony.
First, prepare a soilless matrix
There are many formulas for soilless substrates, which can be taken nearby. Commonly used formulas are:
1. Peat soil: The slag is 4:6. Peat soil can be purchased at the flower market, and the slag can be sieved with honeycomb cinder.
2. Mushroom residue: corn stover: vermiculite: coarse sand is 3:5:1:1. Corn stalks must be broken into small pieces of 2 to 3 cm and soaked in water, and then fermented with other substrates. Add 10 kg of disinfected chicken manure and 1 to 1.5 kg of diammonium phosphate and potassium sulfate per cubic matrix during fermentation. Not less than 20 days, every 7 days.
3. Corn stove: vermiculite: mushroom residue is 3:3:4.
4. Slag: Mushroom residue: sawdust is 3:5:2.
The technical indicators of soilless culture substrate require organic matter to account for 50% to 60%, carbon to nitrogen ratio of 30, p H value of 5.8 to 6.4, total nutrient content of 3 to 5 kg/m2, and total nutrients with nitrogen, phosphorus and potassium as the three elements. main indicators.
Second, prepare cultivation equipment
Use a slightly larger diameter flower pot or a foam box to fill the soilless substrate with a thickness of not less than 15 cm.
Fourth, sowing
First, the soil-free substrate is immersed in water to maintain a matrix water content of 60% to 85 %. Then, the noodle dish is sown, and the substrate is covered by a spreading method of 1 to 2 cm. It should be noted that the temperature suitable for the growth of noodle vegetables is slightly lower, generally 15 to 20 ° C, and 20 to 25 ° C during the day before emergence, not higher than 25 ° C, 10 to 12 ° C at night, 5 to 6 days. Emergence. Generally, it is not suitable for sowing in summer. The best sowing season is in the early autumn and early winter. Of course, indoor planting can be planted by adjusting the temperature.
V. Management
Indoor cultivation of noodle vegetables, before and after emergence, small water should be poured or sprayed with a watering can to keep the ground moist, prevent soil compaction and affect emergence. At the same time, in order to promote emergence and Miao Qi, Miao Zhuang, 2% urea solution can be added to the sprayed water, and the seedling growth effect is very obvious. Noodle vegetables enter the vigorous growth period. Because of the high planting density and the need for water, water should be watered frequently to ensure sufficient supply of fertilizer and water to facilitate stem and leaf growth. When the seedlings grow to 2 to 3 true leaves, the first top dressing should be carried out, and the nitrogen, phosphorus and potassium three-element compound fertilizer should be applied with water at a dosage of 1.5 kg/m2; after 10 to 15 days, the second top dressing is carried out.
Sixth, harvest
The noodle dish is cultivated in the room. When 10 to 16 leaves are grown about 40 days after emergence, it can be combined with the thinning seedlings, and the noodles are usually picked with a knife. In order to increase the output and uniformity, and to extend the supply period, it is advisable to grasp the principle of keeping the big and keeping small when harvesting, and to collect the diligence, but it needs to be flexible. It is harvested once every 15 to 20 days and can be harvested 3 to 4 times.
The above is the whole content of the soilless cultivation technology of noodle vegetables. Welcome friends who are interested to come to Huinong.com to learn more!
