How to grow melons
<h1>1. Choose a method</h1>
Select excellent varieties, and then sow seeds when the temperature is higher than 15 degrees, use nutrient bowl seedlings before sowing, and then apply plantar fertilizer for transplantation, after transplantation, you should control the moisture and temperature, water the compound fertilizer every 5 to 7 days, and timely top the top when flowering, so as not to grow branches, and do a good job of flower preservation and fruit preservation measures.
There are many varieties of melons, but the main varieties that are suitable for promotion and use in various places are: American zucchini, early green zucchini, crisp jade No. 1, Jingdian jasper, black beautiful and other high-yield disease-resistant varieties, farmers can choose according to actual needs.
<h1>2. Sowing method</h1>
Melon likes temperature, heat tolerance, afraid of cold, when the temperature is lower than 15 degrees Celsius growth stagnation, but the high temperature adaptability is strong, in the 40 degrees Celsius high temperature can still have a considerable photosynthesis, so the sowing period of melon as long as the temperature is higher than 15 degrees Celsius can be sown.
<h1>3. Cultivate strong seedlings</h1>
1. Seed disinfection and germination
Generally, 1% copper sulfate or carbendazim can be used for soaking and disinfection. During the live broadcast, it can be mixed with iron excretagram or 3% Bataan powder to avoid underground pest damage.
2. Seedling and sowing
If fine cultivation, you can choose a nutrient bowl or a nutrient bag to raise seedlings, nutrient soil preparation to 1000 kg as the standard, mixed with fine manure 300-400 kg, carbendazim 2. 5 kg (can also choose 200-500 g of methammer or 100-200 g of Bataan raw powder or 100-200 g of iron quenching). 30-50 kg of calcium, 20-30 kg of compound fertilizer, add an appropriate amount of water (with a soil moisture content of 40-50% is appropriate) and mix well, and pile for 5-7 days.
Then sow seeds in bags (bowls), and it is advisable to sow one seed per bag (bowl). The implementation of live broadcast should be applied to the sole fertilizer, each mu of rotten mature farm manure 3000-5000 kg, calcium 40-50 kg, compound fertilizer 30-50 kg. Deep application in the groove or deep application in the pond. Then cover the soil and sow seeds, and sow 2-3 seeds that have been sterilized and germinated in each pond.
<h1>4. Reasonable dense planting</h1>
The planting density of melons depends on the variety. The row spacing of the general dwarf type is: row spacing 0. 60—0. 80 meters, plant spacing is 0. 50 meters, 1600-2200 ponds per acre, 4000-4500 plants are appropriate. The row spacing of the vine type is 1. 50—2. 00 meters, plant spacing is 0. 50 meters, 700-800 ponds and 1400-1600 plants per mu are appropriate. Therefore, when choosing a variety, the majority of farmers must understand whether the variety is short or long. The melons of the nest type (short vine) are thinly planted, and it is impossible to obtain high yields, and the long vine type (strung everywhere) is densely planted, the group is large, the ventilation is not good, it is not resistant to disease, it does not produce melons, and the yield is also very low. Therefore, it is necessary to understand the varieties and determine their planting density according to the varieties.
<h1>5. Planting management</h1>
1. Seedling management
Melon seedlings grow rapidly, especially for seedlings that carry out nutrition bags or nutrient bowls, in order to prevent the growth of the disciples, the water and temperature should be strictly controlled, and the seedlings should be gradually released after excavation, and the temperature during the day should be controlled at 20-25 degrees Celsius, and the temperature at night should be controlled at about 10 degrees Celsius. At the same time, it is necessary to strengthen the management of fertilizer water, every 5-7 days, with compound fertilizer water to water the seedlings, and with methyl frost spirit or nail frost aluminum copper watering, in order to prevent the harm of root rot, to 4-5 true leaves, spray wine with Bordeaux liquid once to prevent powdery mildew and white rust.
2, Ota Management
Seedling transplanting or direct seedlings, in the early stage, we must be diligent in hoeing and ploughing to promote root development, all diseases are derived from the root system, the root system is not developed, the growth is thin, and the disease is relatively heavy. In the future, it is necessary to combine irrigation, medium cultivation, soil cultivation, and fertilization with the theme of strengthening management. At the same time, it is necessary to carry out timely pest control, focusing on the prevention and control of downy mildew, powdery mildew, white rust and root rot. Advocate the use of more ecological pesticides such as Bordeaux liquid, and also pay attention to the use of biological pesticides such as bt emulsion to control leafminer flies.
When the melon grows to 3-5 leaves, it is necessary to pick the heart and manage the whole branch. Generally speaking, the method of "sub-vine" and "sun man" melon is used to make the melon can be supplied to the market one after another. When the melon grows to 5-6 leaves, it is necessary to apply fertilizer in time, and 20-30 kg of compound fertilizer can be applied per mu to promote the growth of roots, vines and young melons, and at the same time irrigate every 3-5 days to keep the soil moist.
3. Hit the top and take the heart
The main vine of the melon rarely blooms female flowers, relying on the sub-vine and the grandchild vine to form a melon, and the sub-vine mostly occurs in the 1-2 sections of the female flower. Therefore, timely topping is the technical key to melon cultivation. After the melon colonization, when the main vine has 4-5 leaves, timely top plucking, after the occurrence of the sub-vine, select 2-3 strong sub-vines, other weak sub-vines are pruned, when the sub-vines to be selected have 5-6 leaves, pick the hearts again, select 3 sun vines on the sub-vines, other weak and small grandchildren are cut off, after the sun vine sits on the melon, leave 2 leaves from the melon to pluck the heart, pay attention to removing the deformed melon, distribute the sub-vines and sun vines evenly, and press the soil blocks on the sub-vines, and the old leaves and diseased leaves are pruned and taken out of the field.
