Afterwards, it is the best time for strawberry seedlings to be grown. In order to cultivate good, disease-free and strong seedlings, we ask the large raspberry farmers to do their best to manage the following seedlings.
1, the cultivation of the parent seedlings
In order to eliminate the nutrient consumption of the parent seedlings and promote seedlings, the old leaves and diseased leaves of the mother plant must be removed in real time, and the flower stems must be removed; at the same time, the plants should be sprayed with 50ppm gibberellin (ie, 20 g/g of gibberellin). Kilogram), spray twice, once every 7 days.
2, real-time irrigation fertilizer
According to the seedling soil dry level, real-time irrigation, adhere to soil moisture in the seedlings, under normal weather conditions, a continuous fine and 3-5 days of watering the seedlings once; when watering can be jointly applied thin fertilizer, request every other 15 to 20 days, apply some thin manure or 0.5% compound fertilizer and urea once in a thin loquat.
3, weeding loose soil and stalks
Real-time weeding and ripping, weed out weeds and strawberries for water and nutrients, benefiting the moisturizing of soil and rooting of seedlings, ensuring the development of seedlings, and incubating the seedlings for raising floating seeds during weeding in real time to prevent rooting. "Floating seedlings"; while grooming the stems and stems of the stems, there is a certain amount of room for development for each stem and stem, and excellent seedlings will occur.
4. Pest control
The main pests of strawberry nursery fields are:
Aphids, red spiders, leaf beetles, Spodoptera litura, leaf spot diseases, etc.
aphid:
When it is produced, it can be controlled by imidacloprid, such as 2500-3000 times of 10% imidacloprid.
Red spider:
Produce early prevention and control, pharmaceuticals can use pyridazinone, acetylene terpenes, such as 15% Chan Ling 1200 times or 57% of alginate 2500 times, in the prevention and control when mixed with 99% Lu Ying 300 times more effective good.
Ye Jia:
When damage occurs, it is treated with 40% virulent EC 800 times, or 5.7% Baishu EC 800 times.
Spodoptera litura:
In the seedling area, traps are trapped to kill male adults, and the next generation of insect populations is eliminated. Four traps per mu are used to trap insects, and the trapping effect is good. Chemicals can also be used to prevent and control, 0.2% Fuda 1500 times, or 40% can be used. The virus died 800 times of EC, or 5.7% of EC 100 times.
Leaf spot disease:
From May to June, it was the peak period of leaf spot disease, and prevention and treatment was conducted in real time. Real-time clearing of diseased parts of leaves and plants, and using 300g/L of oxastrobin, nicotinamide water, granules, 1000 times solution, or 50% nucleus dry suspension agent, 3000 times, or 65% Baitai, water, granules 700 times liquid, or 99.1% green eugenol 300 times mixed with Ye Fu WP 1500 times, or 5% nectonazole WP 1500 times, or 40% Fuxing wettable powder 4000 times liquid spray.
