The round eggplant appears as a "white navel"

Round eggplant "white navel" has the following three reasons: First, due to the recent more cloudy days, weak light in the shed, eggplant can not receive direct light, can only accept the scattered light, even if the eggplant produces pigment, the color is lighter even Whiteness; Second, pruning is not timely and is blocked by the upper leaves. The lack of light in the round eggplant results in poor coloration of the fruit, especially in the umbilicus. Thirdly, there is a large demand for water and fertilizer during the expansion of the eggplant, but many vegetable growers. Concerned that the winter flushing will reduce the temperature of the ground, affect the growth of roots and reduce the supply of fertilizer and water, resulting in insufficient supply of nutrients due to round tomato and poor coloration.

In this regard, it is recommended that growers strengthen management from the following aspects to avoid the appearance of “white navel”.

First of all, reasonable defoliation leaves. Choose fine weather and timely remove dense leaves, old leaves, yellow leaves, etc. around the round eggplant to avoid the branches and leaves from hiding the fruits and reduce nutrient consumption. When picking leaves, follow the principle of “more without squeezing” the upper leaves of the fruit. This ensures the ventilation effect between the plants without lack of light transmission; the leaves of the lower part of the fruit should not be completely removed, and one or two functional leaves may be reserved. In order to ensure the photosynthesis of the plants, the enlargement and coloration of the round tomato fruit are promoted.

Second, the shed film is often wiped and grass curtains are pulled on cloudy days. Timely cleaning and wiping the shed film, increase the transparency of the shed film, even if the cloudy days, but also to pull the straw curtain, according to the temperature within the shed, as appropriate, early to cover the straw curtain, extend the lighting time, ensure the normal coloring of the round tomato fruit.

Third, strengthen water and fertilizer management. The nutrient requirement for large fruit during the expansion period of the round jackfruit fruit increases rapidly the absorption of nitrogen and potassium. The high-end water-soluble fertilizer with high absorption and utilization efficiency can be applied. For example, 963 intelligent expanding fruit special fertilizer (21～8～21) 10kg/ Mu, or Gleda sugar chelating water-soluble fertilizer 8 ~ 15kg / acre, and with the application of functional fertilizers, such as amino acids (photodynamic), chitin (963 smart chitin) fertilizer, improve the quality of round tomato To promote fruit coloring.

Fungi, a large class of chlorophyll - free, can not carry out photosynthesis, heterotrophic lower class of plants. These include bacteria, slime molds and fungi. Their common characteristics are: the plant body has no differentiation of roots, stems and leaves, does not contain chlorophyll and other photosynthetic pigments (except a few photosynthetic bacteria), can not carry out photosynthesis, saprophytic life or parasitic life, that is, heterotrophic life. Most of the reproductive organs are single-cell structures, and the zygotes do not develop into embryos.
