Reporter of watermelon cultivation technology ltd. 20xx/01/01: the list of watermelon cultivation in xx provides an overview of watermelon varieties that have been prepared for watermelon cultivation prior to the cultivation of the watermelon, and of the technological innovation in watermelon harvesting and storage for watermelon cultivation 010030040506. The origins of the watermelon have spread through ancient trade routes to asia, europe and so on, gradually becoming one of the widely grown fruits worldwide. The watermelon, which was transmitted to various parts of the world during the tang dynasty, has been brought into china, thanks to improvements in planting techniques over the years, resulting in a variety of endemic varieties. China's historical cultivation areas are located in the north of china, such as shandong and henan, which are the main producing areas of the watermelon because of its climate and fertile soil. The major producing areas of the watermelon, such as california, mexico and brazil, are also important plantations of the watermelon, where there is sufficient sunlight to facilitate its accumulation. Watermelon is a globally warm and dry watermelon climate that is suitable for cultivation at an average annual temperature of 18-32°c, and neither too low nor too high for growth. The analysis of the economic value of climate conditions grown in watermelon as a summer relief good has led to a significant increase in market demand, especially during hot seasons. The market demand for watermelon is relatively low, but attention needs to be paid to irrigation and pest control, with higher benefits for sound management. Watermelons with different planting costs and benefits are adapted to different markets, and special varieties such as seedless watermelons and small watermelons can improve market competitiveness. In addition to fresh food, watermelon diversity can also be used to process products such as fruit juice and jelly, and to widen marketing channels and add value. Watermelon processing and value-added watermelon species selection by subheading parttwo, a common species known for its high sugar and sweetness, are good for summer breaks and are popular with consumers. Seedless watermelon varieties are free of seeds, easy to eat, suitable for consumers who do not like seeds, and market acceptance is high. The seedless melon black melon, which is rich in meat and water, is one of the high-quality varieties common in the market. The characteristics of the melon species vary from 60 to 90 days in comparison with the maturity of different melon species, with market demand and planting cycles being taken into account. The variety of mature differences is more resistant to atrophy, while others have better defences against anthrax. There are significant differences in the size and shape of watermelon species, such as circulars, ellipses or rectangulars, compared with the disease-resistant nature of watermelon species, affecting market positioning. The size of the fruit differs from the taste and sweetness of the different species of watermelon, either with a high sugar content or with a more fragile taste. Watermelon cultivation with a sense of taste and sweetness is based on the choice of well-drained, fertile sandy soil to ensure the development of roots and promote fruit sweetness. The soil requires that 0102 watermelon be suitable for growth in a warm and sunlighty environment, with an average annual temperature above 18°c to facilitate the maturity of the fruit. Climatic conditions of 03 watermelon have a high demand for moisture and require regular irrigation to keep the soil humid, while avoiding the accumulation of water leading to decay. Subheading parthree soil selection and improved watermelon cultivation, which is pre-pre-planted by hydro-manufacturing watermelons, should be based on well-drained, organicly rich sandy land, in order to ensure healthy root system growth. Watermelon 01 is suitable for growth in micro-to-neutral soils with ph values from 6. 0 to 7. 5, and soils with peracid or alkaline need improvement. Before planting, fully decomposed organic fertilizers, such as composting or green fertilizers, are applied to increase soil fertility and improve soil structure. Treatment of soil using solar or chemical disinfectants to eliminate pathogens and pests and reduce the occurrence of pests. Select the appropriate soil type ph to adjust the application of organic fertilizer soil disinfection seed treatment methods to enhance the resistance of seeds through dressing, while providing the necessary nutrition to promote the growth of seedlings. Seed wrappings use warm water or chemical disinfectants to impregnate seeds to kill the disease on the surface and prevent its occurrence. Placing seeds in warm and wet environments for seedlings to increase the incidence and reduce the onset time. The timing and manner in which seed seed sprouts are disinfected are selected according to climatic conditions, such as spring seeding, which usually takes place at soil temperature stabilization above 15°c. Choosing suitable planting time 01 to disinfect and seed watermelon seeds in order to increase growth and resistance. The seed treatment method, 02 watermelon seeding, includes live broadcasts and seedlings, with the most appropriate method chosen according to the circumstances. The method of sowing is to select the subheading partfour of the section on management of watermelon cultivation, 03, to determine the spacing of the strains according to the characteristics of the species, so as not to overtly cause poor ventilation and disease. Reasonably irrigated and fertilized watermelons during their growth, especially during the expansionary period, to ensure adequate water and nutrient supplies. The management of water fertilizers is carried out in a timely manner, with a view to controlling the number of chickens left to improve the quality and production of watermelons. The whole branch and the chicken are regularly inspected for watermelon fields in order to detect and treat pests and diseases in a timely manner, reduce losses and ensure healthy growth of the watermelon. The point of management of pest control and water fertilizers is that water is needed to properly irrigate watermelons and that proper irrigation ensures the quality of fruit and avoids fibrosis and disease. Scientific fertilization is based on the rational application of watermelon at different stages of growth, with the combination of base and pursuit of fat, promoting healthy growth of plants. Controlling the excessive use of nitrogen fertilizers can lead to watermelons that affect the quality of fruit and require strict control of use. Pest control technique 01 uses yellow stickers to kill insects such as aphids and white lice to reduce the use of chemical pesticides. The appropriate use of pesticides, such as insecticides and microbicides, to control the spread of pests and pests in chemical control measures. Biocontrol technologies introduced natural enemies, such as wedges and spiders, to control the number of pests and protect the ecological balance. Agricultural strategies have reduced the incidence of disease and pests through rotation, deep soil reclamation and timely removal of disease and disability. The subheading of the chapter on watermelon harvesting and storage transport, partfivee maturity determination, is smooth, has clear skinlines, has visible signs of contraction in guatemala, and colour changes from deep to shallow. Observe the appearance of the watermelon by hitting the watermelon to hear the sound, the sound of the mature watermelon is duller, and the sound of the premature watermelon is softer. Accusations on the sound recognition of maturity measure the sugar content of a watermelon using a sugar gauge, which is generally considered to be more than 10 degrees of maturity. When measuring the maturity of the watermelon in sugary form, the chicken that connects the fruit naturally drys up, which is an important indicator of the maturity of the watermelon. The method and time used to observe the drying of the chickens is to select the appropriate weather and time for harvesting to ensure quality, depending on the maturity and variety of the watermelons. Determine the best harvest time to use appropriate tools and methods for harvesting and handling to reduce friction and impact on watermelon skins and prevent damage. Avoid mechanical damage by carefully cutting watermelon vines with scissors or knives, avoid damage to fruit and maintain the integrity and freshness of the watermelon. Watermelons that are stored and transported under the right harvesting methods need to be kept within appropriate temperatures, usually 10-15°c, during transport to prevent the decomposition of fruit. Appropriate temperature control 01 should avoid severe vibrations and bumps in the transport of watermelons in order not to damage the internal structure of the fruit and affect quality. (c) avoiding the use of air-breathing nets or foam bags to package watermelons, reduce friction and collisions and maintain fresh fruit. Watermelons shall be stored and transported in reasonable packaging03 in such a manner as to control their humidity and to prevent the occurrence of fruit impurities or diseases as a result of excessive humidity. The subheading of the chapter on technological innovation for the control of wetting 04 watermelon cultivation, partsix, modern planting technology, applies the smart irrigation system of genetically improved technology, 0103, using genetic editing and molecular breeding techniques to produce new varieties of watermelon resistant to disease, high yield and good quality. The use of sensors and automated control techniques to achieve accurate management of water in watermelon fields and to improve the efficiency of water use. Real-time monitoring of watermelon fields through drones carrying high-resolution cameras prompts detection of pests and growth anomalies. Uavs monitor soilless cultivation techniques, using the trophic cycling system, simulate the soil environment, provide balanced nutrients for watermelons and improve yields and quality. The trophic cycling system uses integrated hydrofertilizer techniques to accurately control the availability of moisture and fertilizers, promote healthy growth and save resources in watermelons. Integrated management of hydro-fertilizers ensures the optimal development of the watermelon environment and reduces the incidence of disease through smart equipment to monitor and regulate the temperature of the greenhouses。intelligent temperature control 010203 management trends using sensors to monitor soil moisture for watermelon fields
