Organic Fertilizers for Spinach Production
Spinach is nutritious. Vitamin A and vitamin C rank the highest among all vegetables, and human hematopoietic substances contain more iron than other vegetables. Whether in the urban or rural areas, it is being favored by more and more people and the planting area is expanding year by year. During the whole growth stage of spinach, a large amount of nitrogen fertilizer (organic fertilizer) is applied. Fertilizer prices are high, and a large number of applications will cause changes in the structure, physical and chemical properties of the soil. Human and animal urine is fully decomposed and decomposed in the soil. The growth period of spinach is short and it is impossible to effectively absorb and utilize it.
It is well known that fertilizer accounts for a significant proportion of the cost of planting. How can growers save this large sum of money? The Golden Baby fertilizer starter (click here for details) will help you achieve this. The organic fertilizer fermented by the fertilizer starter has high fertilizer efficiency, long-lasting fertilizer effect, and will not burn seedlings. More importantly, the source of raw materials for fermentation is extensive, and straw, weeds, dead leaves, and manure urine can all be used. At a suitable temperature (15-20°C), the fermentation process can generally be completed in 3-7 days.
Next, the C/N ratio of the fermented product was maintained at 25-30. Fermentation days: 4-7 days of feces, bark, sawdust, etc. with a high carbon to nitrogen ratio for 25-30 days.
Self-made Fermented Organic Fertilizer in Field Management of Spinach in Different Periods
1, before the spring spinach planted with fermented organic fertilizer for the foot base fertilizer, shallow ploughing, hoeing, leveling. After the flat rake, sowed with wet sowing. If the sowing date is later, dry broadcasting method can also be used. After the two seedlings grow out of two true leaves, the growth rate begins to increase, and they should be poured with shallow watering to keep the soil moist. After the seedlings grow out of 4-5 true leaves, the number of leaves and the leaf weight increase rapidly at the same time, and the nutrient absorption increases. If the base fertilizer is sufficient, it can grow rapidly. The early spring spinach must be covered with plastic film insulation, which can be directly covered on the surface. After emergence, the film is removed or replaced by a small shed. The small arch sheds cover the night cover and the clear rain cover makes the seedlings more visible and more stable. , And time seedlings. Follow-up fertilization water, in the early stage, the organic manure was applied lightly and diligently. In the later period, the available nitrogen fertilizer was applied for 15 days before the harvest.
2. After the summer spinach emerges, it is still necessary to cover the shade net, cover the shade and expose it, cover it as early as possible, in order to facilitate cooling and heat preservation. Watering at the seedling stage should be performed in the morning or in the evening. After 2-3 true leaves, topdressing twice available nitrogen fertilizer. Water should be poured after each fertilization to promote growth.
3, autumn spinach after the true leaves pour 1 water; 2 true leaves, combined with thinning, weeding, pre-fermented application of organic fertilizer.4. Apply sufficient fermentation organic fertilizer before sowing in winter. When 3-4 true leaves are used, proper control of the water is beneficial for wintering. 2-3 true leaves, seedlings 3-4 cm. According to the seedlings and the weather, fertilizers are mainly organic fertilizers. Frost and snow and ice weather should be covered with plastic film and shade net insulation, can be covered with a small arch. After the beginning of spring, choose a sunny day to chase after decomposing organic fertilizer and prevent morning bolting.
