Properties of boric acid for cucumbers
The substance is involved in the metabolic processes of the plant. With its help, useful trace elements are absorbed faster. Boron is necessary for normal photosynthesis of culture. Under its influence, the root system develops faster and becomes stronger. It is necessary for the formation of inflorescences and ovaries. The rudiments of the fruit become stronger, do not crumble.
Boric Acid Solution suitable for cucumbers in the greenhouse and grown in the open field. Increases plant resistance to diseases and pests, as well as weather changes. Since boron is involved in the transport of carbohydrates and sugar, cucumbers containing it in abundance have a more pleasant taste.
Symptoms of Boron Lack
Deficiency of the substance affects the appearance and fruiting of the culture. Rhizomes are underdeveloped. The culture grows much more slowly and does not give lateral processes. The amount of ovary is reduced. Inflorescences may fall. Fruits also change appearance. They are deformed, their taste is reduced.
The vine becomes fragile, prone to necrosis. The immunity of the culture is significantly reduced, as a result of which it becomes vulnerable to diseases and pests. The plant does not bear fruit, may die. These symptoms indicate the need for feeding cucumbers with boric acid.
Excess boron
It is not worth it to abuse cucumbers by watering boric acid. Its excess is no less harmful than a deficit. A plant containing an increased concentration of a substance changes its appearance. Symptoms are different from a deficiency of boron, so it is easy to recognize its excess.
The culture is characterized by a change in the shape and color of the sheet plate. She dies at the edges, becomes twisted. Leaves change color to bright yellow, take the form of a dome. The plant slows its growth, discards foliage. You can determine the excess by reducing the number of female inflorescences on cucumbers.
Application rules
Feed cucumbers boric acid is needed in several stages: during flowering, during the formation of the ovary, during fruiting. Basal dressing is carried out with a minimum interval of 20 days. For processing the culture, you can use boron powder in 10 g packets or special preparations Mag-Bor, Borofoska, Plantafol. When working with granules, the dosage should be strictly observed.
Spraying cucumbers with boric acid can not be carried out in the heat. Optimal - evening time, without wind. Handle greens carefully, from all sides. It is necessary to take into account weather conditions, since rain will wash off the drug, without allowing it to be absorbed. When spraying 10 square meters, about 1 liter of working solution is consumed. For each liter of water, 1/2 tsp is required. powder.
Spraying and seed treatment
Pre-treatment of seeds accelerates their germination, and also strengthens the immunity of the future plant.To work, you need to prepare a solution. In a liter of hot water, completely dissolve the boron granules in an amount of 0.2 g. Soak for at least 12 hours. Wrap seeds with gauze before placing in liquid.
