Unlike other seasons, if you want spinach parsley to grow well in winter, watering and fertilizing is important, and these methods are mastered
Whether spinach and coriander can safely overwinter in winter, master these methods, and you can also eat spinach and coriander in winter
In autumn and winter, many people like to grow spinach and coriander, especially in the countryside, every household will plant spinach and coriander in the yard or vegetable field, these two kinds of leafy vegetables are particularly hardy and can grow until the New Year. As long as you plant a small piece, you will have green leafy vegetables to eat all winter.
A friend asked me that spinach and coriander grow very slowly now, so do you still need to water and fertilize. I would like to say that any vegetable is the same, and if you want to grow better, it is important to have reasonable water and fertilizer.
Autumn and winter season to plant vegetables, the temperature is getting lower and lower, we grow vegetables to cultivate its cold resistance and drought resistance, although spinach, coriander hardy, but in the face of low temperature season, planting methods, water and fertilizer management and spring are very different. If you want to plant spinach and coriander in autumn and winter, so that there are leafy greens to eat throughout the winter, the following cultivation methods should be mastered.
Spinach may be planted sparingly in winter
<h1 class="pgc-h-arrow-right" data-track="8" >: How growing spinach and coriander in autumn and winter differs from other seasons</h1>
1. Planting time
Spinach, coriander in the autumn and winter can be planted in the time range is still quite wide, after the autumn began to plant, if the winter to be able to pick, then before the winter to have a certain amount of growth, the latest should be sown before and after the cold dew (early October). If it is too late, the temperature is significantly lowered, and the growth is particularly slow after sowing. We also plant overwintering stubble, but because the seedlings are too small, they are not edible in winter, mainly supplying the early spring market.
2. Planting method
If you want spinach and coriander to grow well, the humidity in the field cannot be much, otherwise it is easy to get sick. Downy mildew, soft rot, sclerotia, etc. are mainly caused by excessive humidity in the field, and if it is serious, a large number of plants rot and die, which has a great impact on yield and quality. Therefore, it is important to plant leafy vegetables in autumn and winter and keep the field ventilated.
First of all, the sowing density is smaller than in spring, the amount of sowing is reduced by one-third to one-quarter compared with spring, although the planting is relatively thin, but the yield will not be too low, and the spinach and coriander in winter will grow relatively large.
Secondly, seed strip sowing is not sown, and strip sowing is more conducive to field ventilation.
The final seed is sown deeper than the sown, the root system has more space to grow, grows stronger, and is more resistant to cold and drought.
Winter parsley grows slowly but strongly
<h1 class="pgc-h-arrow-right" data-track="30" > two, water and fertilizer management of spinach and coriander in autumn and winter</h1>
In leafy vegetables, spinach, coriander growth time is relatively long, after sowing forty or fifty days to begin harvesting, winter will continue to grow, so the need for scientific and appropriate water and fertilizer management, to ensure its robust growth.
1, the winter temperature is low, watering time should be scientific
Choose to water at noon on a sunny day, and the humidity in the field can be quickly dissipated after watering, which will not make the humidity in the field too large, nor will it lead to a significant decrease in soil temperature.
2, the amount of watering should be small
Spinach, coriander, although the root system in the leafy vegetables is relatively developed, but the depth of the root is still shallow, the root system is mainly distributed in the soil layer of 20cm, so the amount of watering should not be too large, to ensure that the water flows past, the water will also seep out, which also reduces the humidity in the field.
Depending on the soil moisture to determine the frequency of watering, usually not drought and no watering, today the rain is more abundant, watering does not have to be too diligent. However, it is necessary to loosen the soil diligently, increase the ground temperature, and cultivate a strong root system that can resist cold winds and cool down.
3. When fertilizing, the bottom fertilizer should be sufficient, the topdressing is reasonable, and foliar fertilization is very important
Bottom fertilizer: Because the growth time of spinach and coriander is very long, the bottom fertilizer should be applied sufficiently before planting, more organic fertilizer should be applied, and about 2,000 kilograms of decomposed manure should be applied per acre of land.
Topdressing: during the growth of topdressing 2-3 times, do not topdress pure nitrogen fertilizer, pure nitrogen fertilizer can indeed promote the rapid growth of vegetables, but it is not possible to increase the accumulation of vegetable dry matter, and it can not improve its resistance. Therefore, to combine nitrogen, phosphorus and potassium fertilizers, compound fertilizers with higher potassium can be applied.
Foliar fertilization: The temperature is low in winter, the physiological activity of the plant is not so strong, spraying foliar fertilizer, or spraying sugar and vinegar can be used faster, and vegetables will grow better.
4. Fertilization method
The simple fertilization method is to water the fertilizer after spreading, but the fertilizer effect is not very good. If the planting area is not large, you can dissolve the fertilizer first and then apply it with watering.
The coriander in the shed is fine and tall, and the taste is not as strong as the coriander in the open ground
In winter, the last watering of spinach and coriander should be in late November. We all know that wheat should be watered with frozen water, in fact, the leafy vegetables grown in the open, including spinach and coriander, should also be watered with frozen water, which can meet the demand for water for vegetables throughout the long winter, and after watering, the bottom soil can be warmed, and spinach and coriander will not be frozen to death. If you can cover it slightly with shed film or straw before snowfall, spinach and coriander will be fresher in winter picking.
