Asparagus seedlings

The cultivation of green asparagus needs to be transplanted and planted in the field after sowing and seedling cultivation. Therefore, planting asparagus must first cultivate seedlings and lay the foundation. Now its technical requirements for raising seedlings are described below:

The varieties that are suitable for cultivation of green asparagus are "uc800" and "uc157". These two varieties are also suitable for harvesting white asparagus, which is a high-quality, high-product variety that is used for the cultivation of green and white asparagus.

Timely seeding Asparagus sowing can be divided into spring, summer and autumn. The planting in spring from early April to early May, transplanting from early June to early July, and putting into production in the spring of the following year; sowing in late May to early July in summer, transplanting from late August to mid-September, and mid-August Seed sowing in early September, transplanting in the middle and late April, and harvesting in the autumn. It is better to plant seedlings in the spring.

Cultivate strong seedlings, soak seed germination Asparagus seeds before soaking, first with water to remove the wax again, and then soaked in warm water at 25-30 °C 3 days and nights (in summer and autumn soak 2 days and nights), change the water 2-3 times a day. After soaking the seeds, drain the water, wrap it with wet gauze, etc., moisturize and incubate at a temperature of 25-30°C, and after 3-7 days, expose some of the seeds to whiteness.

Seedbed finishing and sowing selection of well-drained, loose, fertile sandy loam soil for seedbeds, one acre per acre to cultivate asparagus, 200 kg of decomposed nitrogen fertilizer, 3 kg of phosphate fertilizer, 2 kg of potassium fertilizer spread on the bed, plowing into the soil, Then use 40% "Asparagus Green" powder 600 times liquid to disinfect the soil and level the seedbed. The seedbed is 120 cm wide and 15-20 cm high. Open a seeding trench every 20 centimeters in the vertical direction on the surface of the bed and 2 centimeters in depth, soak one seed every 10 centimeters in the trench, cover soil 1 centimeter after sowing, cover a layer of rice straw, and use 600 times the “Asparagus Green”. Wet liquid to keep the seedbed moist and bactericidal. In the spring, we must build a small plastic shed to hold moisture in time, and in summer and autumn, we should use a shady shed to cool and moisturize. The use of nutritional seedlings can better improve the quality of nursery. Cultivate strong seedlings. Asparagus sprouts 5-7 days after sowing. After part of the emergence, the straw should be promptly removed and the seedbed temperature should be controlled within 25-30°C. In case of high temperature, the film should be ventilated and ventilated. When the temperature is stable above 20°C, the film can be peeled off, the light can be strengthened, and the strong seedlings can be trained. When the seedling grows to a height of 10 cm and starts to pump the tender stems, it will be applied once every 10 days. The water will be irrigated once in a timely manner, and the weeding will be done timely. Every 10-15 days, a 40% “Asparagus Blue” powder will be sprayed 600 times to prevent it. The occurrence of disease. When the asparagus seedlings have 4-5 strong seedlings, they can be transplanted when the seedling age is about 2 months.
