There are five main reasons that cause carrot fork root to split:
1. Seed quality Chen seeds have weak viability and germination is bad, affecting the growth of the young roots, and some radicles are damaged and easy to produce bifurcations; seeds harvested in the rainy season are prone to embryoless or embryonic dysplasia due to poor pollination. The seeds sown these seeds, the roots of the flesh are prone to bifurcation.
2. There are gravels, bricks, tiles, roots and other hard materials in the soil to hinder the growth of the main root and produce bifurcations; the shallow and hard land of the cultivated layer is susceptible to the growth of the main root, which promotes the growth and development of adventitious roots and produces bifurcations.
3, fertilization excessive fertilizer or non-uniform fertilization, may lead to carrot root apical part of the soil EC value is too high, the root of the root of the high concentrations of soil ion concentration and promote adventitious root growth cause carrot bifurcation.
4. Improper management of watering is irrational. If the dry roots of the carrots are in a dry period without watering, the soil will be too hard and the main roots will not go down and form bifurcations. This is impervious to water or topography when watering. The phenomenon of bifurcation at height is particularly evident.
5. Underground pests damage Earthworms, cockroaches, and other underground pests bite on the main roots of carrots, causing the main roots to be damaged, and promoting the growth of adventitious roots.
Ways to prevent carrot fork root split:
1. Choose the high-quality, high-product varieties with straight roots that are resistant to bifurcations, such as the five-inch ginseng in the new Kuroda, and the five-inch red honour.
2. When buying seeds, choose fresh and full-grown seeds.
3, the plot to deep plowing, deep plowing not less than 25 to 30 centimeters, fine-grained 2 to 3 times, and strive to fine soil; soil preparation not to leak, especially on the ground side. At the same time, it is necessary to pay attention to smashing bricks, tiles, stones and roots in the ground.
4, should pay attention to a reasonable period of reasonable watering, do watering, watering, remember to fill "Happy Valley water."
5, organic fertilizer to fully decompose, fertilization and strive to spread evenly.
6. Pay attention to the prevention and control of underground pests in time to avoid their harm.
