The causes and preventive measures of the latest melon grain collapse

In the process of melon planting, the phenomenon of grain collapse often occurs. The appearance of melon after grain collapse will be seriously affected, which will reduce the commodity value and affect the economic income of farmers. So what is the reason for the collapse of melons? How to prevent it? Let's get to know it with the editor.

First, the reasons for the collapse of melons.

When the muskmelon fruit was sown with fertilizer and water in the early stage of fruit expansion, the fruit expanded slowly, the pericarp aged and hardened, the fertilizer and water supply was sufficient in the later stage, and the muskmelon internal pulp grew rapidly, but at this time the external fruit had aged, and the internal pulp would break the epidermis and cause the melon to crack. After the melon fruit surface was exposed to sunlight, the pericarp aged, hardened and contracted, and the peel produced concentric tortoise cracks on the melon surface after shrinkage. In the later stage of plant growth, the plant was overwatered, the water absorption of the plant was large, and the pulp was swollen, while the pericarp was aging and its flexibility was poor, resulting in fruit cracking. In addition, the lack of water, calcium and boron and other trace elements in the soil will also form cracks.

II. Preventive measures

1. Balanced supply of fertilizer and water

According to the demand for fertilizer and water during the growth period of muskmelon, balanced supply of fertilizer and water, do not blindly watering and fertilization, fertilization should not only apply sufficient base fertilizer to meet the nutrient needs of muskmelon in the early growth stage, but also timely topdressing in the late growth stage of muskmelon to meet the fertilizer requirements of muskmelon in the later stage. When watering, on the one hand, it is necessary to timely irrigate the expanded melon water to promote the expansion of the fruit, on the other hand, after watering the expanded melon water, do not irrigate the heavy water, especially 10 days before picking, so as to prevent the fruit from rapid absorption and cracking or reducing sweetness.

2. Protective blades

Pay attention to protect the leaves near the fruit and use them to block the sun for the melon fruit to avoid cracking due to the aging of the fruit due to direct sunlight.

3. Foliar spraying

Foliar spraying was carried out with strong melon stalk after sitting melon, once every other week, continuously spraying 2-3 feet, so as to improve plant water absorption and fertilizer absorption, improve fruit yield and quality, reduce fruit drop rate, and reduce the incidence of cracked fruit, stiff fruit and deformed fruit.
