The biggest problem in the cultivation of summer spinach is how to overcome the problem of high temperature and rain in summer. The summer spinach planting requires us to adopt a winter-heated greenhouse, which is carried out during the summer break. This not only solves several technical problems in the planting process, but also achieves high economic benefits. Here, Hui Nong School will bring you the key points of planting technology for summer spinach.
For summer spinach, you need to use heat-resistant varieties. For details, please refer to our spinach variety selection course.
I. About land preparation
100kg of potassium sulphate compound fertilizer and 2kg of carbendazim per 667 square meters, evenly spread to the ground, use the rotary tiller to drive into the ground, level the ground, do the north-south planting ridge, ridge height 20-25cm, ridge spacing 50cm.
Or 2,000 to 3,000 kilograms of composted farmyard manure, 20 kilograms of three-element compound fertilizer and 10 kilograms of urea per 667 square meters. It is also necessary to apply 1.5 kg of zinc fertilizer and 0.7 kg of boron fertilizer as base fertilizer. Shallow tillage, made of 1.1 meters wide flat 畦 (including 埂), the 畦 surface must be flat, 畦 not too long, about 15 meters is appropriate.
Cover the unremoved shed film with a sunshade with a light transmittance of 40%.

Second, the management after emergence
1. After soaking seeds and germination, spinach emergence, we need to carry out seedlings and seedlings. After emergence, the areas where the seedlings are too dense can be used for seedlings.
2, watering generally 8 times a day water, depending on the degree of drought. When watering, 5kg of potassium nitrate can be applied per 667 square meters with water. When watering, it should be poured with small water. It should not be flooded to make it difficult to soak the base of the plant.
3. The main disease for controlling pests and diseases is squatting disease. After emergence, plants and ground can be sprayed with 1500 times of bacteria. In the case of heavier onset, 72.2% Plex 600 times solution and 68.75% DuPont Yibao 1000 times solution can be used to irrigate or spray. The main pests are Liriomyza sativae and greenhouse whitefly, which can be sprayed with DuPont Wanling 1500 times solution and 1% aphid clear 2000 times solution.
4, timely spraying of foliar fertilizer can be used Tianda 2116 (leaf vegetables) spray, can also be used to display the brand to protect the harvest 300 times liquid spray.
Third, timely harvest
Because spinach is a fast-growing vegetable, it can be harvested and sold in 45 days. The time is too long, which leads to poor commodity.
Fourth, matters needing attention
1. Planting is done by ridge planting instead of planting.
2. Rain protection should not allow rain to drip to the plants.
3. When there is moss on the surface of the moss, the sunshade net should be removed for a few hours, and the ground should be padded to facilitate ventilation and prevent disease.
Spinach cultivation also needs to pay attention to the field management of spinach, we will not elaborate here, please refer to our spinach field management. I hope to help our vegetable farmers bring high yields and high incomes.
