    Some of the shepherd's cabbage is purple because some varieties are different, it is a variety after subsequent improvement, and the nutrition of the shepherd's cabbage has no absolute relationship with what color it is.

    Differences in breed:

    Although shepherd's cabbage and shepherd's cabbage are both called shepherd's cabbage, the shape is similar, and both are eaten by humans, but strictly speaking, the two are not the same plant, first of all, the two shepherd's cabbage belong to the cruciferous family, but shepherd's cabbage belongs to the genus Capsule, and shepherd's cabbage is also called the big root shepherd's cabbage, which belongs to the genus 蔊 [hǎn] vegetable.

    Summary. Pro, there are several reasons for this, one is that mustard greens like to grow in cool temperatures, and the most suitable temperature for growing is 15-20. When the temperature is lower than 15, the ability of mustard roots to absorb water decreases, and the growth is restricted, so after transplanting, the regreening is slower and even wilts.

    Second, the root system of mustard mustard without grafting before transplanting is underdeveloped, and the ability to absorb fertilizer and water after transplanting is poor. Therefore, mustard seedlings should be fertilized once before transplanting, preferably 5 to 7 days in advance. In this way, after changing the growth environment, mustard seedlings can rely on the nutrients they carry to help them pass the slow seedling stage.

    Third, mustard seedlings carry viral diseases virus diseases are very easy to occur in the mustard seedling stage, which affects the growth and development of the root system in the early stage of the disease, makes the mustard become shriveled, and then the leaves and veins appear diseased.

    Dear, there are several reasons for this, the low temperature mustard greens like to grow in cool orange temperatures, and the most suitable temperature for growing is 15 20.

    Fourth, watering too often mustard likes a moist environment to grow up, but it is not Li Wei often afraid of standing water. When watering too often after transplanting, and leakage or flood irrigation, it will cause waterlogging in the field, which will bring many disadvantages to the survival of mustard.

    First, try to raise seedlings in advance, transplant them before the local temperature drops, and make the mustard seedlings after hand pure fiber planting smoothly return to green. Or if the temperature becomes low after transplanting, cover it with straw or straw curtain in time to keep warm and moisturize.
