Planting Time of Onion in Northern China
There are two traditional planting methods of northern Chinese onion: seedling raising in late autumn, seedling raising or planting in May-June of the following year; The harvest of the two methods is usually from July to June, 10, which will be delayed until the Spring Festival.
Efficient planting method
1, seedling raising
The seed quantity of scallion is 2-4 kg per mu. Before sowing, you can soak the seeds to accelerate germination, and cover the soil about 2 cm after sowing. From sowing to digging, the bed surface should be wet. According to the soil moisture, water should be poured 1-2 times, and the amount of water should not be too much, so as to avoid the seedlings growing white. Before the seedlings overwinter, 1 times of frozen water can be poured, and 40 kg of "Feiyoute" broad-spectrum microbial compound fertilizer or 1-2 kg of "Feiyoute" microbial inoculum can be evenly mixed with other fertilizers and applied to the soil to ensure the nutrient demand of onion seedlings, strengthen roots and prevent diseases, and ensure the safe overwintering of seedlings. After turning green, irrigate 1 turn green water, and enter the peak growth period. Combined with watering, topdressing "Feiyoute" broad-spectrum microbial fertilizer for 2-3 times, weeding and interplanting. "Fei You Te" has comprehensive nutrition, loosens the soil, reduces the incidence rate, prevents overgrowth, is conducive to the healthy growth of seedlings, and is a fertilizer for cultivating strong seedlings.
Step 2 plant
Let's continue to introduce the topic of this issue in depth.
The planting period depends on the variety and local climate, and it can be rotated with wheat, barley, spring cabbage and other crops. Green onions were originally planted in a ditch, and the distance between ditches depends on the length of green onions. After the onion seedlings are put in the ditch, it is beneficial to slow down the seedlings by spreading "Yufit" broad-spectrum fertilizer and covering the soil.
3. Tian Tuan management
(1) water and intertillage
The weather is not very dry, so it is generally not suitable for watering. It is necessary to strengthen intertillage weeding, loosen topsoil, store water and conserve moisture, and promote root system development. Drain water during heavy rain to prevent rotten roots, yellow leaves and dead seedlings. After beginning of autumn, water lightly, and water in the morning and evening. Later, with the plant governor, you can gradually increase the frequency of watering and stop watering one week before harvest.
(2) Topdressing
Generally speaking, it starts in autumn, combining irrigation and soil improvement. "Feiyoute" broad-spectrum microbial fertilizer can be topdressing 20 kg per mu. "Feiyoute" contains 200 million beneficial living bacteria per gram, which has strong functions of nitrogen fixation, phosphorus dissolution, potassium dissolution and slight solubility. , improve soil fertility, provide complete nutrients for root absorption and utilization, break soil hardening, improve aeration and improve water and fertilizer retention capacity.
Step 4 harvest
Different varieties, different regional climate, different harvest time. Generally, when the growth of the outer leaves basically stops, the leaves turn yellow-green, and 15-20 days before the soil is frozen is the suitable harvest time for the green onions.
Through our introduction, I believe that everyone has a deeper understanding of when and how to grow green onions in the north, and the flower will be constantly updated. I like that we remember to collect them and share them.
