Wheat intercropping spinach is an important means to make full use of land resources, climate resources, increase multiple cropping index, and increase economic income.
First, sowing time The best sowing date for wheat intercropping spinach is from late September to early October. The spinach sown at this time can safely pass winter and can be guaranteed to be listed in March. If sowing is too late, the growth of spinach before winter is small, winter is not safe, and it is delayed to come out in April of the coming year, and it is easy to twitch and reduce the value of commodities.
Second, pre-sowing preparation Spinach before October 10 can be planted dry land. However, the soil must maintain good sensation (can be made in advance), the general soil moisture in the 70% to 80% (that is, soil into a group, fingers without dripping) immediately after sowing or watering. The spinach planted on October 10-20 is subject to seed treatment, ie soaking with warm water at a temperature of about 20°C for 12 hours on the day before sowing, and removing the seeds for later sowing to reduce the emergence period.
Three, sowing wheat intercropping spinach every 2 meters is 1 mile, each pod 3 groups, each row of wheat 1 line of spinach, wheat spacing 10 cm. In the reserved row for sowing wheat, use a single eyelid to evenly inject spinach seeds into or ditches and spread them evenly. About 1.5 kilograms of seeds are used per acre, so that the seeds can be mixed and mixed with sand. After the broadcast, it was flat and watered afterwards. The corn will be planted in the middle and late May of next year after the spinach harvest.
Four, spinach field management
1. Seedlings. When the spinach grows 2 leaves, the young plants are planted with a spacing of about 3 cm.
2. Fertilizer management. There are no special management measures for spinach, with watering wheat, the soil temperature stable in the next year at 5 °C combined with pouring back to Qingshui topdressing nitrogen fertilizer.
3. Harvest. In March of the following year, spinach grows to about 20 centimeters in time for harvest.
Five, the benefits of wheat intercropping spinach
1. Raise the ground temperature and maintain soil moisture. Wheat and spinach are in a symbiotic stage from October to March. The symbiosis of the two crops increases ground coverage, prevents excessive evaporation of soil moisture, improves soil moisture content, and changes the microclimate in the field, thus increasing the safe wintering of crops. The insurance factor also limits the space for growing weeds in the field.
2. Wheat can make full use of edge advantages to increase production. By changing the row spacing of wheat, without losing the number of acres of wheat, it was symbiotic with the spinach at the early stage. After the spinach was removed at the end of March, the wheat could use the edge advantage to increase the yield.
3. Interplant corn in advance. Intercropping spinach can be planted in the middle of May with a wide range of corn, prolonging the period of corn growth, and preventing corn from being cut because of the low temperature during the late growth period, so that the sowing date of wheat will be advanced in the next year.
4. High economic efficiency. General mu can increase two or three hundred yuan.
