When was the onion planted? How to plant it?

In our Enshi area, chives are one of the vegetables that every household must grow, which can be planted all year round. It is oily green all year round, spicy and delicious, and it will be more delicious when cooking. Therefore, we have a local saying that "onions are not ripe". There is also a legend that Shennong tasted hundreds of herbs and found shallots, which are added to flavor every day when cooking various dishes. Therefore, shallots are also called "harmonious grass".

Onions are mainly edible tender leaves and scallions, which are rich in nutrition and can remove fishy smell and taste. Not only that, but also the effect of strengthening stomach and sweating. Onion has strong adaptability, short growth cycle and strong tillering ability, and can be tillered and transplanted many times, which is very beneficial to repeated planting. First, the planting time is drunk. Mei Xueyan's shallots are transplanted all year round, and there is no specific arrangement for planting stubble. If it is planted in a large area, it is necessary to consider the specific planting time for sales.

1. Spring stubble: Generally, it is transplanted in mid-June of 5438+0, and harvested from early March to mid-late April. At this time, plastic film mulching is suitable for planting, which can speed up the growth of shallots and supply them to the market as soon as possible.

2. Summer stubble: Generally, it is transplanted from mid-April to early June, and harvested from early May to the end of July. This crop can be interplanted with other tall crops, which can avoid using sunshade nets, reduce input costs and make up for the market gap in summer.

3. Autumn stubble: Generally, it is transplanted from early August to late September, and harvested from mid-September to165438+1early October. At this time, the transplanting weather is dry and the temperature is still high, so attention should be paid to cooling and moisturizing. Other crops can be used to cover the replanted land or use sunshade nets.

4. Winter stubble: Generally, it is transplanted at the beginning of 10 ~ 10, and harvested in10 ~ February. At this time, it is the cold winter. Because of the low temperature, the growth of leek becomes very slow. In order to supply the market, we can use the autumn delayed harvest to meet the market supply before and after the Spring Festival.

Second, the growth characteristics of shallots are warm, moist, cold-resistant, heat-resistant, afraid of drought, waterlogging and strong light. They do not require much soil, and grow vigorously at 18~23℃.

1, temperature: Onion grows slowly when it is higher than 28℃ and lower than 12℃, and it is easy to stop growing and enter a dormant state when it is hot in summer.

2. Moisture: The distribution of the root system of shallots is relatively shallow, and the water demand is small, so they are afraid of drought and waterlogging. Therefore, water should be done several times more, and drainage should be done in time when there is much rain.

3. Illumination: When the light intensity is moderate, the onion grows well, and it is easy to age under strong light, which leads to the aging of onion leaves, the decline of quality and the deterioration of taste.

4. Soil: Onion has low requirements for soil, but in order to avoid repeated cropping, it is generally necessary to change the land in about 2 years. Plots with deep soil layers, good drainage and fertile soil grow more vigorously.

3. Onion seedlings can be propagated by seeds, usually in March-April or 9- 10, and the whole growth period takes about 80 days; It can also be transplanted in bulbs, and there is no strict requirement on time. The whole growth cycle takes about 50 days. Bulb transplantation is basically used in Enshi area.

1. Variety selection: We mainly have two local varieties, one is four-season rice onion and the other is Sichuan chives. If the sales value is considered, varieties with good resistance, thick leaves, fast growth and strong flavor can be selected for planting according to local characteristics.

2. Seed propagation: It is advisable to keep seeds in the first year or buy fresh seeds through formal channels. If the storage time is too long, the germination rate is particularly low, and some even do not germinate. The germination rate is the fastest when the temperature is around 13~20℃.
