How do you grow summer spinach? Please explain the growing method in detailThe summer spinach growing method can refer to the following list:
1. Protective measures for summer spinach:
Summer is hot and rainy, virus diseases occur heavily, and spinach is not tolerant of high temperatures, so measures such as shading and rain sheltering should be taken during cultivation.
Method one: On a greenhouse or arched shed whose old film has not yet been removed, add a layer of shade netting 2 meters wide with a light transmittance of 60%-70%, covering one panel and leaving one uncovered, to lower the temperature inside the shed.
Method two: Add insect-proof netting. Aphids and small brown planthoppers are the vectors that spread virus diseases. Using insect-proof netting to keep these virus-transmitting vectors out of the greenhouse is one of the main techniques for growing summer spinach. Before planting, add 60-70 mesh insect-proof netting around the arched shed or on the south side of the greenhouse, so that ventilation is not affected while virus-transmitting vectors are safely kept out of the greenhouse.
2. Choose heat-tolerant spinach varieties:
Generally choose k4, k5, k6, k7 produced by the Dutch company Bejo, and Sheng Bifeng produced by Syngenta; these varieties can generally tolerate high temperatures of 34°C, with k7 performing best. The sowing period is from May to September.
3. Ridge cultivation of spinach:
Practice has shown that spinach grown in summer is most afraid of dampness. Grown in beds, it is prone to stem rot, while grown on ridges, the base of the leaves has good ventilation and is less prone to disease. Generally, form a ridge every 50 cm, plant 2 rows per ridge, dibble one hole every 5 cm, sow 2 seeds per hole, and use about 1 kg of seed per mu.
4. Fertilizer and water management for summer spinach:
Spinach likes fertile, slightly alkaline soil with high humus content, so organic fertilizer should be applied heavily during cultivation. Generally apply 1000 kg of decomposed chicken manure and 2 kg of boron-magnesium micro-fertilizer per mu; for topdressing, potassium nitrate fertilizer is best, applied at 15 kg each time. For watering, pay attention to watering when dry and hoeing after watering.
5. Pest and disease control for summer spinach:
Summer spinach is prone to stalk rot, anthracnose, and so on, which can be prevented in advance by spraying solutions such as Daconil M45, carbendazim, and thiophanate-methyl once every 7 days. When preventing virus diseases, attention should be paid to killing insects to prevent insect transmission. Work should also be done well on shading, rain protection, and prevention of soil drought, and more organic fertilizer, potassium fertilizer, and micro-fertilizers should be applied. Spray Zhibingling, Virus A, and so on once every 7 days to prevent the occurrence of virus diseases. The main pests are American leafminers, mites, aphids, and so on, which can be sprayed with Miteclear once every 7 days.
6. Harvesting summer spinach:
When spinach grows to 20-30 cm tall, it should be harvested promptly. Summer temperatures are high, spinach is not tolerant of high temperatures, and it can spoil at any moment, so harvesting should be done sooner rather than later.
