Field management 1. Fertilizer and water management Spinach likes fertile, moist, neutral metaalkali, soil with high humus content, therefore, it is necessary to re-apply organic fertilizer. Generally, every 667 square meters uses rotten organic fertilizer 1000 to 1500kg. If the soil is acidic, 20 to 30kg of lime can be added per 667 square meters. Immediately after the spinach grows out of the true leaves, it will be poured with a light stool. Afterwards, with the growth of the plants, the topdressing concentration will be gradually increased. However, it should be applied when the soil is dry to prevent the soil from growing wet and causing diseases. Fertilization should pay attention to the principles of light application, diligence, and early lightening. In the early stage, more organic manure was used, that is, manure was decomposed, and manure application should be stopped 15 days before harvesting. During the late period of growth, the urea should be topdressed for 2 to 3 times, and each application of urea should be 5 to 10 kg. Promote leaf cluster growth, increase yield, improve quality. 2.
