When will Yangjiao honey melons mature and go on the market? When is the best month to plant? Attached planting method

Yangjiao honey melon is a muskmelon variety, early and middle-ripe variety, like sheep horn, hence the name sheep horn honey. So when will Yangjiao honey melons mature and go on the market? When is the best month to plant? The planting methods selected for you are as follows:

Yangjiao honey melons are ripe and put on the market in August under natural conditions.

In which month is Yangjiao honey melon planted?

Sheep horn honey is a kind of thin-skinned melon, which is characterized by high sugar content and good taste. However, this variety has some problems, such as premature senescence, serious cracking, poor disease resistance and so on. Many melon farmers give up planting.

Many measures should be taken at the same time, focusing on preventing premature senility of muskmelon.

The growth period of Yangjiao honey melon is relatively long, if the weather is bad or improper management, it is very easy to occur premature senescence in the later growth stage, yellowing from the lower leaves, weakening photosynthesis, reducing organic nutrition, seriously affecting the yield of muskmelon. So, how can we avoid premature senescence of plants?

First, grafting to prevent premature senility and dead trees

Muskmelon root system is easy to cork, root regeneration ability is weak, disease resistance is poor, especially in continuous cropping, muskmelon premature senescence and dead trees are prominent, which seriously affected the yield and quality of muskmelon. In order to prevent these problems, Master Li used pumpkin as rootstock for grafting to improve root disease resistance and reduce the occurrence of diseases. When grafting melons, you should pay attention to the following points:

First of all, grasp the sowing time of rootstocks and scions. According to Master Li, generally speaking, pumpkin rootstocks are sown about 15 days earlier than Yangjiao honey melons, and melons are sown for about 5 days, and the two cotyledons can be grafted when the leaves are flat. The method of grafting is also very simple, and the method of top grafting of watermelon is the same, so we will not introduce it here. Master Li said that the affinity of sheep horn honey and pumpkin is good, and the survival rate of grafting is very high. what we need to pay attention to is to strengthen disease prevention. The scion and rootstock can be sprayed 800 times with 75% chlorothalonil the day before grafting to reduce the pathogens that seedlings may carry. After 2 days of grafting, 75% chlorothalonil 800x solution mixed with 72% streptomycin sulfate 2000 fold solution was sprayed again to prevent the disease from infecting the wound.

Secondly, the environmental regulation after grafting. Master Li said that after grafting melons, special attention should be paid to the management of temperature and humidity in the shed, and it is generally necessary to set up an arch shed in the shed to facilitate timely adjustment of the environment in the shed, rapidly improve the temperature and humidity in the shed, and facilitate the healing of the grafting interface. Within 3 days after grafting, the small arch shed must be sealed and shading should be strengthened to keep the air humidity in the shed at 90% Rue 100%, so as to prevent the scion from losing water and wilting, affecting the healing of the interface; the temperature should be controlled at 28-32 ℃ during the day and 20-22 ℃ at night. After 3 days, the arch shed can be opened during the day, so that the grafted seedlings can see light properly, promote photosynthesis, improve the nutritional status of grafted seedlings, and promote the healing of grafting interface; at this time, the temperature can be reduced to 26-28 ℃ and 18-20 ℃ at night. About 7 days later, the wound basically healed and could be transferred to normal management.

Second, strengthen management to prevent premature senility

The quality of management is the key factor to determine the growth status of muskmelon. If vegetable farmers want to strengthen management and avoid premature senescence, they can start from the following aspects:

1. Deep ploughing the soil, reasonable watering and fertilization, and creating a good growth environment for the root system are the basis to avoid plant premature senescence. Generally speaking, per mu, 8-10 cubic meters of rotten manure, 50 kg of compound fertilizer and 50 kg of nutrient source are used as base fertilizer, and the soil is turned more than 30 cm deeply to ensure uniform application of fertilizer. Before planting, ditch or hole application of biological bacterial fertilizer, such as anti-bacterial 968 strong seedlings immortal, Dayuan ground rooting, fertile field growth, etc., can inhibit bacteria, reduce the number of pathogens and promote root development. After melon planting, attention should be paid to controlling water and fertilizer, covering plastic film late, ploughing and ploughing to improve soil permeability, which can effectively promote deep root system, form strong root group, improve root system ability to cope with adverse environment, and avoid plant premature senescence. During the growth period, attention should be paid to topdressing and replenishing nutrition in time. Before fruit setting, if the plant growth is weak, you can apply stimulating antibacterial 968 fertilizer at seedling stage to enhance seedling growth, which is conducive to the cultivation of strong trees; after fruit setting, you can apply high potassium water-soluble fertilizer with water, such as lighthouse, Haolipu, aromatic, chitin, etc., once every 10 days, 5-8 kg per mu, to improve nutritional supply and promote fruit expansion.

two。 Increase the row spacing, increase the functional leaves, and improve the ability of plants to produce organic nutrients. In the process of plant growth, the nutrition supply of leaves is the key to determine the yield of muskmelon, especially the variety of Yangjiao honey, Master Li specially increased the row spacing when planting, the width of the operation row is about 1.2 meters, and the plant spacing is 0.5 meters, which can greatly improve the light transmittance between plants. promote plant photosynthesis and provide more adequate nutrition for fruit expansion.

On the basis of improving the light transmittance between the rows of plants, Master Li adopted the method of side branches to increase the number of functional leaves, improve the supply of organic nutrients and avoid premature senescence. The method of keeping lateral branches is to retain most of the lateral branches with 7-8 leaves from the bottom, and to keep 2-3 leaves from the lateral branches, so as to increase the number of functional leaves of the plant and ensure the nutritional supply of muskmelon during fruit expansion.

3. Pay attention to the maintenance of leaves in the middle and later stage.

In the middle and later stage of plant growth, that is, the melon expansion and maturity stage, the plant reproductive growth is exuberant, which needs to consume a lot of organic and inorganic nutrients, the burden of roots and leaves is heavy, the nutrient reserve is small, and the resistance is weakened. At this time, attention should be paid to strengthening leaf maintenance, such as spraying chitin 1000 times, Leduo foliar fertilizer 6000 times, etc., once a week to supplement foliar nutrition and improve leaf activity, which is very good for preventing leaf aging and avoiding plant premature senescence.

In addition, we should also pay attention to avoid drug damage, hormone poisoning and other damage to the leaves. When spraying, avoid using sensitive agents, do not mix too many kinds of pesticides, spray evenly to avoid drug damage.

Careful management to prevent deformities and cracking of melons

Yangjiao honey melon, like other thin-skinned melons, is prone to crack and deformity. Through years of exploration, Master Li focused on strengthening management from the aspects of pollination time, keeping melon nodes, water and fertilizer management, reducing deformities and cracking melons, and improving the rate of fine melons.

First of all, choose sunny weather to dip in melons. Environmental condition is an important factor affecting the rate of fine melons. Master Li said that melons dipped in melons must choose sunny weather, when the plant growth is exuberant, the nutrition supply is sufficient, the activity is strong, the growth rate is fast after sitting on melons, and the rate of fine products is high; if you catch up with continuous cloudy days, you should appropriately adjust the position of melon knots to avoid the effect of even cloudy days on dipping melons.

Secondly, choose the appropriate position of retaining melons. The position of remaining melon nodes directly affects the yield and maturity of muskmelon. If the node position of sitting melon is low (5mur6 nodes), the lower leaves of the plant are few, and the nutrient supply is insufficient in the early stage of fruit development, so that the longitudinal growth of fruit is inhibited, while the fruit expands faster in the later stage of development, resulting in small and flat fruit. If the node position of sitting melon is too high (15mur16 nodes), there are more leaves below the fruit and less upper leaves, which is beneficial to the longitudinal growth of the fruit at the initial stage of fruit development, but the lateral growth in the later stage is inhibited due to lack of nutrition, resulting in abnormal fruit. Therefore, melons should be left in the middle of the stem, and the suitable melon nodes should be located in the 12th section of 7Mel.

Finally, strengthen management to prevent cracking melons. When the melon grows to the size of an egg, that is, 10 days after pollination, melon cracking occurs most seriously. during this period, special attention should be paid to temperature control and fertilizer and water management to avoid cracking. During this period, the daytime temperature can be controlled at 25-30 ℃ and the night temperature is about 15 ℃. After four or five days, the melon enters the rapid expansion period, and the daytime temperature can be raised to 30-33 ℃ to promote the expansion of melon.

Yangjiao honey melons must not be watered and fertilized during the "dangerous period", so as not to aggravate the cracking of melons.

Strengthen disease prevention according to the characteristics of varieties

Yangjiao honey melon is delicious, but its disease resistance is not strong, prone to powdery mildew, brown spot and so on. Disease mainly lies in prevention, once it occurs, it is not easy to cure. Therefore, in prevention and control, we mainly pay attention to these three aspects.

First of all, the greenhouse environment should be regulated to create an environment that is not conducive to pathogen infection. High humidity is the most likely to lead to diseases. With the increase of external temperature, reasonable watering should be done, ventilation should be strengthened and humidity in the shed should be reduced.

Secondly, enhance the disease resistance of the plant. Reasonable watering and topdressing, promoting root growth and paying attention to leaf maintenance, chitin, alginic acid, nucleotide and other spraying or root irrigation can be selected to improve the function of roots and leaves and enhance plant stress resistance.

Finally, chemical control should be reasonable. In the usual greenhouse management, there are few sunny weather diseases, so broad-spectrum fungicides such as chlorothalonil and Amisida can be sprayed every half a month or so to prevent diseases; in cloudy days, the frequency of medication should be appropriately increased and sprayed once every 7-10 days, which can have a good effect on disease prevention.
