How to grow a good spinach
Spinach cultivation is more, but many farmers report poor post-plant growth, poor quality, and low yields. In order to obtain high quality and high yield, it is technically appropriate to grasp the following aspects: Reasonable choice of soil spinach is neither acid nor alkali, and neutral is better. When the pH is below 5.5, the seedling growth is slow and the leaf color is yellow. Non-glossy, poor root system. If the soil is more acidic and the soil is too acidic, it should be combined with 100-150 kilograms of lime for Mushi in order to reduce the acidity. Variety selection should be based on different cultivation seasons to select the appropriate species, Qiutian should choose better heat-resistance Sitiaoshu, etc., Chunxi should choose round leaf spine. To grasp the suitable sowing period, spinach and cool climate, poor germination under high temperature, such as the temperature of 35 °C, the germination rate is less than 20%, so under normal climatic conditions, should start batching in stages in September. Early sowing is better after seed soaking and germination. Strengthen the management of fertilizer and water production to avoid soil drought, and often maintain a certain degree of soil moisture. The requirement of fertilizer for spinach is total fertilizer, in which the ratio of N, P and K is 2:1:2.5. Before the land is plowed, 50 mu of farm manure such as manure and manure is planted, and about 25 kg of superphosphate is used. Top dressing is based on the growth condition. Determined to slightly increase nitrogen fertilizer is conducive to growth.
