Melon cultivation, cracked melon, how to prevent it
The thick-skinned melon flesh is sweet and juicy, with high sugar content, rich flavor and fruit shape, and is resistant to transportation. It is a good fruit and is popular among consumers. At present, the thick-skinned melons have a large planting area in our city and are one of the important industries for farmers to increase their income. However, in recent years, we have learned that in the production of muskmelon melon, the cracking melon phenomenon of muskmelon is more common, which leads to the decline of the quality and commerciality of melon, which causes certain economic losses to the melon farmers. Now I am about to enter the result period of thick-skinned melons. In order to help the farmers to solve the problem of thick-skinned melons, the causes and countermeasures of the cracked melons are summarized as follows: Cause of cracking melon 1. Variety At present, most of the farmers use hybrids of thick-skinned melon and thin-skinned melon, the purpose is to improve the high-humidity resistance of thick-skinned melon by hybridization with thin-skinned melon. If the genetic factors affecting the development of the peel are just provided by the melon, then the peel development of this variety is not sufficient, and it is easy to produce cracked fruit. 2. Inadequate supply of fertilizer and water The fruit expansion period is a key period for the water demand of muskmelon, and the imbalance of soil water supply is an important cause of fruit cracking. In the second expansion period of the fruit, if the soil continues to drought, during the period of large water irrigation, the water in the plant is excessive, and it is easy to produce fruit cracking. In addition, in order to prevent melon seedlings from growing in the early stage, excessive control of water in the early stage of melon growth caused water shortage during fruit expansion, and the melon skin became prematurely hardened. If the fertilization water is too much in the late stage of expansion, the inside of the melon will grow rapidly and the crack will appear in the peel. 3. Temperature and humidity in the shed When the peel begins to harden, if the conditions of low temperature and high humidity are encountered, the daily average temperature is lower than 15 °C or the night temperature suddenly drops, the peel will harden slowly, the development is not full, and the fruit enters the second. After the puffing period, as the internal organization of the fruit increases, a fruit cracking phenomenon occurs. 4. The method of using the fruit is not used. In order to increase the fruit setting rate and increase its growth rate, in order to increase the yield, most of the fruit is used. Due to the uneven spraying, repeated spraying and excessive concentration, the growth of the inside and outside of the fruit is uneven. 5. Soil and trace elements are insufficient. Silicon and boron are essential elements for cell wall development. The application of silicon fertilizer at the bottom and spraying of boron fertilizer on the front surface of the flower are conducive to the full development of the peel. Due to the existence of continuous cropping for many years, the soil itself is deficient in boron and calcium deficiency, and farmers do not pay attention to boron and calcium fertilizers, resulting in cracked melons. Measures to prevent cracking 1. Selection of excellent varieties The selected varieties should be resistant to low temperature and low light in the early stage, with early maturity, high yield, disease resistance and high resistance; high fruit setting rate, high quality and high sugar, good taste and beautiful fruit shape. 2. Do a good job of fertilizer management In the process of planting thick-skinned melon in early spring greenhouse, it is necessary to balance irrigation, especially during the fruit expansion period, which is the peak period of water demand for muskmelon. Drip irrigation can be used to ensure water supply and improve water use efficiency. It takes the most water and fertilizer to enter the expanded melon period. The most important thing is to properly control the nitrogen fertilizer and re-apply phosphorus and potassium fertilizer. The fruit netting is formed to reduce the water supply for a week or so, and the water supply is increased after the netting formation period, and the nitrogen fertilizer and potassium fertilizer are applied. When the fruit is ripe, it is necessary to control the moisture, which is conducive to improving the quality of the melon. 3. Warming and dampening Thick melon fruit is stable after sitting, because the temperature is low at night, pay attention to cover shed insulation. At the same time, it is necessary to pay attention to ventilation and cooling when it is sunny, which is conducive to the full development of the peel. In case of cloudy and cold weather, it should be properly ventilated to make the skin fully developed and reduce the cracked melon. Greenhouse cultivation can be covered by plastic film, which is beneficial to reduce air humidity and reduce disease occurrence. 4. Proper use of sitting fruit spirit Because of the different manufacturers of fruiting spirit, the use of its products is not the same. It should be applied strictly according to the specified concentration to avoid excessive concentration. Spray or peony should be uniform, not repeated or excessively applied. At the same time, it should be used with it, not for a long time. 5. Adding organic fertilizer, applying calcium and boron to increase organic fertilizer, applying biological bacterial fertilizer, has a good promotion effect on improving soil structure and improving soil and trace element supply capacity. For melon plots with soil compaction and slow water seepage, watering and topdressing can be combined. The deep soil-free soil conditioner can break the soil compaction, deepen the tillage layer, increase the soil permeability, and play the role of protecting fertilizer and water, solving and reducing crop physiological diseases. At the same time, high temperature weather should pay attention to foliar supplemental calcium supplementation. 6. Rainproof and sun-proof In the production process, the melon fruit should be prevented from being drenched by rain or directly exposed to the sun to prevent the skin from hardening. When the fruit is exposed to the sun, it can be shaded with newspapers to prevent direct sunlight. This also prevents green spots on the surface of the fruit and makes the fruit beautiful. In short, the cracked melon phenomenon of muskmelon can seriously affect the quality of melon and its economic benefits, which should cause the attention of the farmers and timely and effective prevention.
