Grapes are an economic crop. In recent years, the planting area has also been gradually expanded. The phenomenon of fruit cracking occurs in the process of grape planting. This not only leads to a decline in the quality of the grapes, but also affects the economic benefits of the grapes. Why do crackers appear? This is mainly due to the fact that the fruit that is in close contact with the fruit is partially fragile. After experiencing heavy rain during the mature period, the inside of the fruit produces turgor and cracking. So how to prevent or reduce the emergence of this phenomenon? After the heavy rain, the soil moisture content will inevitably increase, then, whether to use the soil moisture detector to determine the soil moisture, so as to analyze the phenomenon of reducing grape cracking?
The determination of soil moisture by a soil moisture detector revealed that during the maturation period (the end of July) of rose, rose, and other varieties, the amount of rainfall was large, and cracking occurred easily. This is because the pericarp or root sucks rainwater into the fruit pieces and the bulge develops in the fruit pieces and cracks from the cracks in the peel as a result of close development. In addition to fruit cracking, such as rose, rose, etc., fruit crack strength is related to fruit peel strength and water pressure, the influence of cultivation conditions on peel strength cannot be ignored. The intensity of peel is affected by the sunshine, ventilation, and fertilizer in the garden. Park dark, poor ventilation, high humidity, too much nitrogen fertilizer will lead to weakened fruit peel and cracking occurs. Rapid rainfall (or irrigation) after drying also contributes to the occurrence of cracking.
The soil moisture tester also measured the soil moisture of the Kyoho cultivars. It can be clearly found that the soil conditions and the amount of fruit set have a great influence on Kyoho's cracking, among which the soil conditions have the strongest influence. Due to poor drainage in clay soils, dry and wet changes are intense and there are many crackers. In particular, the sunny days after the rain make the temperature rise sharply and adversely affect the fruit. Excessive fruit can also produce cracks.
Therefore, in order to prevent this phenomenon of cracking and reducing the quality of grapes, it should be properly irrigated to maintain a certain amount of soil moisture, anti-crack fruit is very obvious. According to the detection test of the soil moisture detector, not watering not only increased cracking, but also caused more leaf scorching, lower sugar content and poor quality. In addition, when the fruit enlargement, the growth stagnation in the hard nucleus stage is obvious, and the fruit granules are swollen rapidly in the later stage and are prone to cracking. In particular, when the transition to the dry period occurs after the rainy season, irrigation is performed very early to prevent rapid water changes and prevent fruit cracking.
