Collard greens planting and management technology
Collard greens in Shandong generally known as "big head cabbage" "cabbage", but was called "stomach vegetables" I still I heard for the first time. The original often eat kale, it itself contains a lot of vitamins can be very good repair gastric mucosa, to prevent gastric disease.
Really, I've learned a lot! The kale planting range is wide, both north and south are planted, and there are many kinds of kale. Then, share with you the planting techniques of kale.
①Selection of varieties
The quality of varieties determines the yield of the crop as well as the quality, and there are many varieties of kale. We have to choose the right variety to plant according to the local growing environment and conditions.
When choosing seeds, we have to choose seeds that are full of particles, free of disease and damage for planting, which is more conducive to the germination and emergence of kale, and can make it grow better!
②Planting time
Kale adaptable, cold hardiness, heat resistance is also good, but it is suitable for the growth of the temperature is about 20 ℃, so we will choose according to its growth habit in April, September each year to plant collard greens. Because the suitable environment at this time is most favorable to the development of kale.
③Selecting and preparing the land
Kale is adaptable, there are no strict requirements for the soil, basically what can be planted, but in line with the purpose of high-quality and high-yield, it is best to choose the soil is deep, fertile, humus-rich plots of land for planting, water retention and fertilizer retention capacity is good for the preferred.
We put the choice of plot first to organize, you can pack the field of messy debris, clean up, deep turning the land, loose soil is conducive to kale emergence from the ground, out of the bud fast and good.
④Sowing method
The tidied up land is fertilized with enough bottom fertilizer to make a border, and then the treated seeds are evenly spread on the border, covered with a layer of fine soil, plus a bit of straw, which can be moisturized to improve the rate of seedling emergence.
The kale grows leaves, we timely remove the straw, wait until the growth of 2, 3 leaves, you can inter-seedling. Remove the weak and yellow seedlings, leaving the strong seedlings, and when it grows to about 10 centimeters, it can be transplanted.
The day before we decide to transplant, we can pour a moderate amount of small water to make it moist, is in order to start the seedling is good to pull up, try to avoid harming the young root system of the kale, there is also the root system is best to bring a little bit of wet mud, planted when good survival.
⑤Field management
After transplanting, we have to pour seedling water in time, so that the seedlings can be soothed, and more close to the soil, the survival rate is higher.
After the kale seedlings are planted and survive, we don't need to water often, we can water ourselves according to the dryness of the soil and the weather. The best state is that the soil is dry and wet, which is favorable to the growth of the crop.
If we encounter a lot of rain, fields with stagnant water, we need to discharge in a timely manner, so as to avoid poor breathing of the roots of kale, rotten roots, affecting the growth of the crop.
The demand for fertilizer in kale varies according to the growth stage, but the demand for fertilizer is greatest in the wrapping and knotting period, so it must be fertilized at this stage.
It's best to have well-rotted farmyard manure at home, which can be combined with a little nitrogen fertilizer and applied at the same time, which can satisfy the demand for nutrients in kale cores.
6 Pest Control
Kale is a leafy vegetable and often suffers from pests and diseases, such as cabbage worms, aphids, and nightshade moths. If found not timely treatment, a very short time can scourge finished.
We want good control of pests and diseases, we have to observe more, look at the leaves, look at the heart of the leaves, the emergence of insect eggs, insect feces, it is necessary to start early, and strive to let it die in the bud, you can properly use some medicine. When the kale package heart tight, we can harvest .
It actually, like the cultivation of cabbages, the cultivation of kale should also put more effort on water and fertilizer and field management. Only in this way, the taste of kale grown can be better and the yield can be higher!
