Spring spinach is a necessary science, and today the writer shares with you the high production techniques of spring spinach。
1. Selection and planting of high-yielding varieties of spring spinach. A spinach type of spinach type should be selected for spring spinach cultivation. In the early spring, when the surface layer of the soil is unfrozen by 4 to 6 centimetres, it should be shown as early as possible, with the preference of “opposite seeding”. The appropriate planting period is generally determined by meteorological information, and the average daily temperature rises to 4°c - 5°c, which is generally appropriate in the central part of my province in early march。
2. Land as a whole. The plots planted for spring spinach shall choose the plots that have not been planted for crossfacing vegetables or other field crops, which shall be used as base fat in time for the application of corroded corsets, together with nitrogen, potassium and 30 kg of fattening, and shall then be ploughed, dredged, flattened to the ground, made up of flats of approximately 1. 3 metres wide, and prepared for planting。
3. High-yielding seeding of spring spinach. The temperature is still relatively low when spring spinach is planted, and if seeds before seeding are not immersed in seedlings, it takes more than half a month before seedlings are planted, reducing leaves in the long term, thus affecting yields. Thus, so often in production, seeds are immersed in hot water for five to six hours, recovered at 15 °c ~ 20 °c, and washed with warm water once a day, three to four days. The method of sowing is usually long-term short spring spinach, with small plantations, with 5-6 kg per acre. In the early spring, it is advisable to use wet seeding, first to fill the bottom water, and then to sow the seeds after the water has been leaked, then the soil, which is about 1 cm thick. The evaporation of soil moisture has been reduced and temperature-preserving as a result of the lax soil cover of the plume. Seeds are in a warmer, wet and well-ventilated environment and can grow early。
