Bifurcation causes and prevention 1. Soil quality and cultivation. Because the soil ploughs are too shallow and the underlying layer is too hard or has a hard object, the main roots are hindered and damaged by insect pests, and lateral roots are promoted. The main root and lateral roots are hypertrophied at the same time, and bifurcations will occur in the future. 2, the fertilizer is not fully decomposed. Incompletely decomposed fertilizer contains a large amount of uric acid, which burns the main root and causes the lateral roots to become irritated and grows. The basal fertilizer is not evenly distributed, which also impairs the growth of the lateral roots of the main roots to produce bifurcations. 3, planting distance is too wide. The summer and autumn radishes are less bifurcated, but autumn and winter or winter and spring radish bifurcation is more because the weather in these seasons is particularly conducive to the growth of radish. If the density of the cultivars is too broad, the leaves will produce more photosynthetic products and more naturally. Bifurcation phenomenon. To prevent radish from branching, we must do a good job of cultivating the soil deeply to keep the soil loose and soft. Apply sufficient organic fertilizer, and evenly spread these fertilizers into the soil. According to the requirements of each species, it is suitable for close planting. Heart-warming reasons and prevention of radish sprouts are an over-ripe phenomenon. This phenomenon is related to the following factors: 1. Early-maturing varieties have more chances than late-maturing varieties. 2, radish cultivated in light sandy soil will appear earlier than radish cultivated in semi-sediment and loam soil. Poor drainage of the soil, uneven application of base fertilizers and top dressings, or excessive fertilizer production will produce heart problems. 3. Improper sowing time, high temperature and drought during the growth period. 4, radish line spacing is too large. Preventive measures: timely sowing, close planting; selection of soil quality, uniform fertilization and balanced supply of water, so that the roots of radish in a stable and well-formed conditions formed, the heart will be a rare phenomenon. Causes of breakage and prevention of rupture of fleshy roots are the result of uneven soil moisture supply during radish growth. During the growing period, the radish was insufficiently treated with high temperature and drought, which caused the tissue hardening of the cortex of the radish root. By the late radish growth, the temperature was suitable, and the sunlight was sufficient. The parenchyma cells in the xylem of the radish meat roots quickly split and expanded, and the hardened cortex did not grow accordingly. As a result, the cortex was cracked at the top. In addition, excessively viscous or hard soil, or coarse sand, groundwater levels in high environments, and underground pests such as yellow larvae larvae gnaw through the roots of the skin, these environments will cause the root skin to leave some small traces, Adding unpleasant black lines with harmful substances. Prevent radish cracking and rough skin, the most basic is to choose a good soil, keep the soil loose, according to the weather and radish growth performance, timely and uniform water supply, so that radish growth and meat root formation process is not short of water, no shortage of nutrition, no shortage The air is also not squeezed by the soil.
