The invention discloses a fluorine-free durable super-hydrophobic cotton fabric finishing agent. The fluorine-free durable super-hydrophobic cotton fabric finishing agent is prepared by mixing the following components: modified silicon balls, isocyanate, a catalyst and a solvent, wherein the diameter of the modified silicon balls is 10-5000 nm. According to the fluorine-free durable super-hydrophobic cotton fabric finishing agent disclosed by the invention, the chemical bond joining is utilized to effectively improve the fastness between the coating of the cotton fabric finishing agent and the cotton fabric substrate, and fluorinated compound or solvent is not used; based on the hydrophobic modified silicon component and the chemical reaction between isocyanate and hydroxyl, the finished cotton fabric is strong in hydrophobicity and has a certain washing durability, free of toxic and expensive fluorinated compound or solvent, wide in source of raw materials, certainly compatible with other textile finishing auxiliaries, and capable of being applied to the functionalized after-finishing field of the cotton fabric; the cotton fabric finishing method disclosed by the invention is simple, feasible, and suitable for large-scale application and promotion.

The invention discloses a ground growing and vertical frame type combined cultivation method for watermelons, and belongs to the technical field of agricultural planting. The method comprises the following steps: step 1, constructing a greenhouse; step 2, performing soil preparation and fertilization; step 3, raising seedlings; step 4, determining planting spacing, and performing field planting ina suitable period; step 5, constructing a quadripod, performing pruning and vine guiding, performing pollination, and performing watermelon reservation; step 6, performing fertilizer and water management; step 7, preventing and controlling pests and diseases; and step 8, performing timely harvesting. The method provided by the invention utilizes a greenhouse frame to keep warm and take shelter from rain, and avoids the problem that pollination is affected in the flowering and fruit-setting periods of the watermelons because of overcast and rainy low-temperature weather, so that normal pollination and fruit setting can be performed on the watermelons; the ground growing and vertical frame type combined cultivation is used, watermelon vines are guided onto the greenhouse frame in a verticalframe type; after the watermelons set fruits, the watermelons can be put on the ground without the need of hanging the watermelons, so that leaf areas of photosynthesis of the watermelons are increased in a limited space, and growth and expansion after the watermelons set the fruits are facilitated; and meanwhile, the planting density of the watermelons is increased, and the yield of the watermelons, the use ratio of land and economic benefits of watermelon farmers are increased.
