Question 2: How many days does spinach sprout? Hello? For your information: According to your description, you planted spinach on August 9th.
Take an area as an example: the temperature is 23~35 degrees on August 9, and 25~33 degrees on August 13. For spinach with big leaves, it is in the season of high temperature and rainy, so it is a little difficult to emerge. I estimate that it will take more than 7 days to appear. Please be patient.
When planting spinach in high temperature season, in order to germinate normally, it is best to take shade, shelter from rain and drainage facilities.
Thank you for your question.
Question 3: Can I eat spinach in winter? The seeds will germinate in a few days. Do seeds need to be covered with plastic film? 5 minutes low temperature, need plastic film blanket. It takes a long time for spinach to germinate, usually about 10 day, and it will take longer if the conditions are not enough. You'd better let it sprout indoors and then transplant it out.
Question 4: How many days does the spinach seed germinate now? As long as the soil moisture is good, it can germinate in three or four days.
Question 5: How long can spinach seeds germinate in the ground? Spinach seeds germinate in the ground for about 6-7 days.
Question 6: How often should spinach seeds be fertilized after germination? It is safer to fertilize spinach after half a month of germination. If applied in the bud stage, it is easy to burn buds. After 15 days, Henry water-soluble fertilizer can be directly applied, and 5 kg per mu can be applied, which can reduce the fertilizer cost of greenhouse planting.
Question 7: When to sow spinach, when to plant spinach and when to plant spinach.
1, planting time of autumn spinach
Autumn spinach-usually sown in August and September, can be harvested in batches 30-50 days after sowing. Early maturing and heat-resistant varieties should be selected, such as plowshare, Huabo 1, Guangdong round leaf, spring and autumn big leaf, etc.
2. Planting time of overwintering spinach
Overwintering spinach is generally sown in the first ten days of10-165438+10, and harvested in batches around the Spring Festival. It is advisable to choose mid-late maturity varieties with strong winter, late bolting and strong cold tolerance, such as round leaf spinach, late leaf spinach, Huabo 1, Liaoning round leaf spinach and so on.
3. Planting time of spinach in spring
After the spring, the temperature rises above 5℃ to start sowing, and the suitable sowing time is March, and the harvest can be achieved 30-50 days after sowing. Late bolting, big leaf in spring and autumn, round leaf in Shenyang and round leaf in Liaoning should be selected.
4. Planting time of spinach in summer
Summer spinach is usually sown in stages from May to July, and harvested continuously from late June to mid-September. Huabo 1, Chunqiu Daye and Guangdong Round Leaf with strong heat resistance, fast growth and difficult bolting should be selected.
Question 8: When will spinach sprout, blossom and mature? If spinach is going to blossom, it should be planted in the last ten days of 10, and it will blossom in April and mature in May of the following year.
Question 9: How many days does the seed germinate for a week or so?
In summer and autumn cultivation, it is necessary to accelerate germination and sowing, otherwise it is difficult to ensure the success of seedling raising. Because the optimum temperature for the germination of oil wheat seeds is 15-20℃, it will not germinate if it exceeds 25℃ or is lower than 8℃. The simple and feasible germination method is to soak the seeds in clear water for 4-6h, then scoop them up and drain them, and put them into * * * to accelerate germination. You can choose the following three methods.
The method of accelerating germination of river sand is to spread wet river sand with a thickness of 20-30cm in the shade, then remove the soaked seeds from the surface of river sand, spread wet river sand with a thickness of 1-2cm, and cover it with fresh vegetable leaves.
Hang the soaked seeds in a thermos with ice to accelerate germination, add water and ice to reach 15-20, wash the seeds every 1 day/time, change water and add ice.
The soaked seeds are wrapped in gauze and put into the refrigerator at 15-20℃ by the method of accelerating germination at low temperature in the refrigerator, and washed 1 time every day. It takes about 2-4 days to accelerate germination, and 60%-70% can be planted after germination. Direct seeding can be used in suitable seasons, and arch shed can be used for heat preservation in winter and spring. In summer and autumn, it is best to use sunshade nets to shade and cool down.
