The main roots of the radish roots swelled in the early stage, causing the outer cortex to gradually harden, the internal cells to grow slowly, the rainy water in the swelling stage was sufficient, the secondary xylem parenchyma cells rapidly expanded, and the pericarp hardened, the swelling could not keep up and the cracked outer skin caused the cracking roots. .
Countermeasures Pay attention to watering evenly during the growth of the main root of the radish.
The roots of the radish, the lateral roots of the radish, expand into a "bifurcation" phenomenon. Its formation is caused by many reasons: 1 soil physical and chemical properties are poor, the soil layer is shallow, many gravel, hindering the normal growth of the main root, the increase of nutrients to the lateral roots leads to bifurcation. 2 The organic fertilizer is not fully decomposed, and the heat generated by the fermentation of the fertilizer in the soil burns out the growth point of the main root, causing the growth of the lateral roots. 3 The seeding is too dense, the seedlings are not timely, the roots of the radish are crowded, and the main roots are bent, resulting in the growth of lateral roots. 4 In the agricultural activities such as weeding, the main root growth point is damaged and the root part is forked.
The countermeasures are to select the deep, loose and fertile soil to cultivate the radish, and pay attention to the intensive cultivation; select the high-quality and decomposed soil and fertilizer as the base fertilizer; plant the seedlings and the time seedlings and seedlings.
In the autumn, the radish is easy to appear in the environment of high temperature and drought, dry before dampness, or plots that are planted too early and harvested late.
For the cultivation of radish, it is advisable to choose loam with deep soil layer and loose and fertile soil, and balance the fertilizer and water after the radish is “broken belly†to avoid uneven drying and wetness; the main root is fully grown and harvested in time.
Black heart, black skin black heart, black skin mainly have two reasons: 1 black rot. After the radish meat is very damaged, the symptoms in the middle and the middle are not obvious. After the incision, the catheter becomes black, the internal tissue is dry and rot, and the pith is mostly black and hollow. 2 soil layer knot, the application of organic fertilizer is not fully decomposed, resulting in radish black heart, black skin.
Countermeasure 1 Sowing in a timely period, avoid continuous cropping, and avoid planting in low-lying areas. Black rot incidence of early discharge of 72% streptomycin regulation 3 times, 7--10 days 1, even spray 3--4 times. 2 Intensive cultivation, avoid soil compaction; apply high-quality decomposed organic fertilizer as base fertilizer.

We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
