How to Fertilize Watermelons for Sweeter Fruit? Master the Five Fertilization Methods
1. Farmyard manure method: When preparing the land and applying base fertilizer, apply plenty of farmyard manure with a complete nutrient profile, such as chicken manure and sheep manure. The watermelons grown this way are uniform in size, good in flavor, and high in sweetness. 2. Potassium bacteria method: Microbial inoculants containing potassium bacteria such as "Manyuanchun", bio-organic fertilizer, and black-plus-white biological fertilizer are compound high-tech microbial fertilizers. Applied in stages with formulas throughout the entire growth period of watermelons, they can make the watermelon leaves dark green, the fruit shape regular, and the sweetness increase by 1 to 1.5 degrees.

How to grow seedlings of seedless watermelon? Practical experience shared
Seedbed establishment The seedbed land must be chosen in a place that is sheltered from the wind, facing the sun, high in terrain, and close to a water source, for ease of management. The seedbed is 2.5 m wide and 0.15 m deep, and the length is determined as needed. When establishing the seedbed, care should be taken to make its bottom as flat as possible. Before making the pots, spread a layer of sandy soil on the bottom of the seedbed to facilitate lifting the seedlings.

How to apply formula fertilization to hybrid watermelons
Hybrid watermelons require high water and high fertilizer. According to calculations, producing 1000 kg of watermelons requires 5 kg of N, 2 kg of P2O5, and 5 kg of K2O. If hybrid watermelons are planted on medium-fertility soil with a yield of 3000 kg per mu, then 15 kg of N, 6 kg of P2O5, and 15 kg of K2O are required. When fertilizing, achieve

Detailed Explanation of Key Techniques for Growing Large-Fruit Watermelons
1. Site selection 1. Soil quality: Choose sandy soil that is loose and well aerated. Black soil with a sand content of about 30-40% is best. For clay soil, increase the number of tillage operations to improve soil permeability; autumn plowing is best. Once the vines have grown to more than 30cm, do not deep-plow, to prevent

Detailed Guide to Hand-Pollination Techniques for Watermelon
I. Selection of Node Position For watermelons grown under protected cultivation, the fruit-setting node position can be lower; for open-field cultivation in spring, the fruit-setting node position should be higher; for early-maturing varieties, the fruit-setting node position is low; for late-maturing varieties, the fruit-setting node position should be higher. The suitable fruit-bearing node position depends on the variety and climatic conditions. Generally

Key Points of Transplanting Techniques for Muskmelon Cultivation in Small Tunnels
① Transplanting Timing The transplanting timing is an important factor determining early maturity and high yield. Transplanting too early makes it difficult for seedlings to survive due to low soil temperature; transplanting too late fails to achieve the goal of early maturity. The earliest transplanting time should be when the local average daily temperature rises to 10°C and the average daily temperature under the plastic film on the high ridge at a depth of 10 cm reaches above 18°C. It is advisable to choose clear, warm and windless weather for transplanting, and immediately cover with the tunnel film for insulation after transplanting.

Key Points for Seedling-Stage Management in Muskmelon Cultivation
① Temperature management: Before the seedlings emerge, a relatively high temperature (25-30°C) is required. After 70%-80% of the seedlings have emerged, lower the temperature to 20-25°C during the day and 15°C at night, because from seedling emergence to the flattening of the cotyledons, the hypocotyl grows fastest during this period, and this is the stage when the seedlings are most prone to

What are the common problems when transplanting muskmelons?
(1) Preparation of the planting site. After the previous crop is harvested, plowing should be done immediately. Because muskmelons require a loose and deep tilth layer, the plowing depth should be 25-30 cm, and should not be shallower than 20 cm. Deep plowing can thicken the loose soil layer, increase soil pores, activate the soil, and

Preparatory Work and Transplanting Techniques for Greenhouse Cultivation of Muskmelon
① Transplanting at the right time plays an important role in the early ripening of muskmelon and in improving economic returns. The transplanting period is closely related to the ground temperature inside the greenhouse at the time, so the transplanting period differs from region to region. In the middle and lower reaches of the Yangtze River it is in early to mid-March, in North China in late March, and in cold regions such as the Northwest and Northeast in early to mid-April.

Control Methods for Anthracnose in Muskmelon Cultivation
It is a fungal disease. Muskmelon anthracnose occurs severely in the middle and late stages of plant growth, mainly damaging stems, leaves and fruits. After harvest, infected fruits will rot in storage and transport when exposed to a humid environment and become unfit to eat. On diseased seedlings, semicircular brown lesions appear on the edges of the cotyledons.
