Many vegetable farmers in Donglulu Village, Gaoliu Township, Qingzhou, have reported that they have grown up with large navels and even cracks. This affected the selling of eggplant and caused a lot of losses. Through analysis, the author believes that this is caused by the physiological imbalance of the plant. It is recommended that the vegetable farmer pay attention to the following points in the management, you can avoid the occurrence of large navel.
The night temperature in the shed is too high.
As the greenhouse insulation measures are now doing well, new films, new grasshoppers, new cotton quilts, etc., caused a high temperature in the greenhouse at night. Because there are two kinds of situations when the night temperature is high:
(1) The high night temperature will lead to poor flower bud differentiation and the formation of short-stemmed flowers, which will cause the navel of the eggplant to be even cracked.
(2) A high night temperature can also lead to excessive consumption of nutrients by photosynthesis during the day, which can cause malnutrition in organs such as flower organs, affecting the quality of pollination and fertilization, and can also form a large navel. Therefore, it is recommended that vegetable farmers take measures to properly reduce the night temperature, so that the greenhouse temperature is 27°C-30°C during the day and 14°C-18°C during the night.
Anther concentration is too high.
Many vegetable farmers have lax requirements on the concentration of the anthers and the time spent on flowers, which is another physiological cause of the big navel. The current point of the anther concentration can choose the following formula: 3 two water against 2ml 2,4-D, 5ml anti-dropping factor, 1ml gibberellin and 3ml love more income and moderate music appropriate amount. At the same time, according to the changes in weather and the flexible adjustment of temperature, it is advisable to spend a little time on the day before or on the day of flowering. It should not be too late.
Plant physiological deficiency.
Boron is an important trace element that is directly involved in flower bud differentiation. If the plant lacks boron, it will lead to poor flower bud differentiation, resulting in a large belly button and sometimes cracking. There are two main factors that cause boron deficiency:
(1) Soil lacks boron.
It is best to use 200-400 grams of large-grain boron for the preparation of the base fertilizer, and then should be sprayed 1000 times high boron, 7-10 days once, even spray 2-3 times, while the amount of water with the application of boron sand acres 1 kilogram is appropriate, boricine is added in time to improve the quality of flower bud differentiation.
(2) Root injury.
The root system is not good, and the absorption of boron is hindered. In this case, appropriate measures should be taken according to the causes of the root injury. For example, the bio-fertilizer + rooting root + macro and micro-elements in the one-piece multi-recovery full nutrition water-soluble solution Fertilizers, or sea-green-fertilizers containing alginic acid, can alleviate the symptoms of large navels caused by boron deficiency.
