According to reports, the lack of zinc and iron in greenhouses will produce a "yellowhead". It is recommended to pay attention to the use of trace fertilizers in basal fertilisers, to use the principle of high-energy electrons and plant electron polarity induced by the photosynthesis of plants to increase cell division and molecular synthesis. And nutrition to match the digestive level, accelerate the metabolic frequency, activate the plant nutrient system to produce fertilizer effect.
After the symptoms appear, spraying with zinc, iron + plant cellular immune factors promptly improves the plant's resistance to stress and can cause viral DNA fragmentation and apoptosis. Root damage caused by the "yellow head", it is recommended to reduce the amount of watering, to pour water, fertilizer to raise the roots and protect the vine bio-fertilizer, humic acid fertilizer + 600-800 times the new high fat film-based, to prevent germs Infection, improve the ability to resist natural disasters, make the root system of cucumber return to normal growth as soon as possible, thus prompting the leaves to turn green.
