Temperatures soared after summer, watermelons, melons, tomatoes and grapes were the most vulnerable to cracks. Many farmers thought that water was watered, but the blindly controlled water was too small to sell. Today, the most practical fission-proof package in the field is made clear, and the whole process is operational。
I. The three core causes of the fibrosis
1. Shrimp drying and wetting
After a prolonged drought, one-off heavy water pours in, and fruit and meat expands at a rate far above the rate at which the bark is spread, which is the most common problem in open-air orchards。
2. Nutrient imbalances
Nitrogen fattening can lead to long leaves and thin walls of fruit cells; lack of calcium and calcium, and lack of resilience of the fruit skin, which breaks with a little rain。
3. Extreme temperature fluctuations
During the day, the sun is hot, the night is cold, the skin is hot and cold, and the larvae and the guacamole in the medium and long term are prone to cracks and cracks。
Ii. Daily prevention steps in the field
1. Scientific control of water and rejection of heavy water fill
Small water is used to water, either in the morning or in the evening, to avoid high noon temperatures. The soil is kept dry and wet, and the surface is covered with straw, the membranes are locked to the soil moisture level and the damp differential is reduced. During the rainy season, drains were dug ahead of schedule to eliminate the plume in the fields。
2. Equivalent fertilizer and increased fretilin resilience
The expansion period reduced pure nitrogen fertilizer such as urea, with emphasis on high potassium water solution, combined with calcium glycol + flute boron face spraying, once in 7-10 days and twice in a row. Calcium hardens the walls of cells, and boron promotes calcium absorption and increases the anti-push capacity of the fruit sheet from within。
3. Physical shade protection
An open-air guacamole covers the light with a sunnet to prevent hard spots in the skin from being burned with the sun, which is the height of the posterior fracture. The sheds are ventilated to stabilize the temperature in the sheds, day and night。
Iii. Remedies in which slight fibrosis has occurred
Broken fruit has no commercial value and is directly removed to avoid the depletion of tree nutrients. The rest of the healthy fruit immediately stopped the water, and the leaves were sorely sprayed with fertilizers, while the roots were soaked to the root that it stabilized the suction rhythm and prevented a mass outbreak of fibrosis。
Iv. Warnings for growers
Many feel that the fissures are completely cut off, that the severe drought of the soil leads to premature crop failure, that the small sweetness of the fruit's head falls, and that rational water stabilization + calcium supplementation is the key to a steady harvest。
