Techniques for Growing Watermelons with Organic Ecological Substrates
The organic ecological solid-matrix cultivation mode is a high-efficiency, low-cost soilless cultivation technique successfully developed by China's scientific research units during the "Eighth Five-Year Plan" period. Dozens of hectares have been promoted throughout the country and good results have been achieved. It is particularly suitable for the development of soilless cultivation of protected land in economically underdeveloped areas. The main principle of the organic ecological solid matrix is ​​to mix high-temperature fermented and disinfected organic nutrient solution such as chicken manure and cake fertilizer with rock wool, river sand and other solid culture substrates, and then put the organic ecological solid matrix into a cultivation tank. In containers such as cultivation pots and bags, a drip irrigation hose is fixed on the cultivation container, and the traditional nutrient solution is replaced with a clear drip irrigation. After the fruit is set in the watermelon, multiple compound fertilizers are applied several times according to the fertility condition. According to relevant experimental data, the quality and yield of watermelon produced by using this new technology without soil cultivation are not significantly different from conventional nutrient liquid culture. The cost of fertilizer application is reduced by 60% compared with traditional nutrition cultivation, and the nitrate concentration of the effluent from the cultivation container is greatly reduced. In international environmental standards, it avoids pollution to the environment. Disclaimer: Some articles in this website have been transferred from the Internet.
