What about the latest turnip fork? Prevention methods of radish bifurcation

I believe that many vegetable farmers often have a problem in planting radish, that is, radish bifurcation, radish bifurcation will seriously affect the quality of radish, and there is market price. Therefore, when planting radish, we must prevent radish bifurcation in time, so what is the cause of radish bifurcation? How to prevent it? Let's take a look at it together with Xiaobian.

1. Seed quality

When sowing, select old seeds, such seeds are weak in vigor and poor in germination, which will affect the growth of young root apex, and some radicles will be destroyed and easily form bifurcations. The seeds harvested in rainy season are easy to form embryo-free seeds or poor embryo development seeds due to poor pollination. When these seeds are sown, the fleshy roots are easy to diverge.

Preventive measures: choose high-quality and high-yield varieties with straight fleshy roots and difficult branching, so as to avoid branching when planting, try to choose fresh, full and fully developed new seeds of the current year, and try not to choose old seeds of the next year.

2. Soil causes

When the soil always has hard things such as gravel, bricks and roots, the growth of fleshy roots will be hindered and bifurcate. The main roots of shallow and hard plots are easy to grow and hinder, which promotes the growth and development of adventitious roots and bifurcates.

Preventive measures: Before planting radish, the plot must be deeply ploughed and carefully harrowed, not shallower than 25 cm. After many times of fine harrowing, ensure that the cultivated layer is deep and loose. At the same time, it is necessary to pick up hard sundries such as bricks, stones and roots in the soil in combination with soil preparation.

3. Fertilizer and water management shall not

Excessive fertilization or uneven fertilization may cause radish root tips to be affected by high concentrations of soil ions and promote adventitious root growth and cause carrot branching. If the radish taproot is not watered in time during the expansion period of drought, the soil will be hard and the taproot cannot be formed into branches.

Preventive measures: the application of farm manure must be fully decomposed before application, chemical fertilizer must be evenly spread, sufficient water supply should be ensured during the main root expansion period to avoid excessive dryness of the soil, watering must be thoroughly watered.

4. Underground pests

Mole cricket, grubs and other underground pests bite the taproot of carrots, causing the taproot to be destroyed and causing adventitious root growth to diverge.

Preventive measures: In the period of radish rhizome expansion, it is necessary to timely irrigate to control underground pests such as white grubs to avoid damage. The pesticide should be used to irrigate roots with high and low toxicity pesticides such as phoxim to reduce pesticide residues.

The above is an introduction to the causes and preventive measures of radish bifurcation. I hope it can help you. If you want to know more about it, please pay attention to us.
