As the saying goes, "Spring is the year's plan." It is a good time for all kinds of fruits and vegetables to raise seedlings artificially. Only by cultivating high-quality seedlings can we ensure high yield and high efficiency of fruits and vegetables. The preparation work before raising seedlings is very important and can be divided into the following two items:
1. Seedbed finishing method
After selecting the seedling plot, we should repair it in time:
1.1Thoroughly clean up the straw, weeds, gravel and other debris in the field;
1.2Combined with soil preparation and application of foot seedbed base fertilizer, it is recommended thatSelect silicon, zinc, calcium and magnesium products (200-300 ㎡ per 20kg) with a small amount of compound fertilizerFirst, spread the fertilizer evenly, then loosen the soil deeply to apply the fertilizer deeply, and then refine and level it;
1.3Use chlorothalonil or carbendazim to sterilize the seedbed with drugs, and then make the bed with tools such as rakes.

Soil configuration of nutrition
Usually, special substrate can be selected, or fertile pastoral soil, carbon enzyme chelate or seedling strengthening agent, mineral bacterial fertilizer, coal ash or plant ash, etc. can be used. For example, pastoral soil and peat soil are mixed 2:1, and seedling strengthening agent or root soil is added in an appropriate amount,Silicon, zinc, calcium and magnesium 25 kg/bag (best crushing) can raise 20000~30000 seedlings, mix evenly.
Warm tips:
2.1Select plots without germs and eggs, and have not planted melons and vegetables in the past 3 years, and take 5-10cm of soil underground;
2.2Disinfect the soil, mix it evenly into the soil according to the amount of 80 grams of powder added per cubic meter of nutrient soil, then cover the plastic film for 2-3 days, uncover the film and ventilate for 2 days before sowing;
2.3When preparing nutrient soil, do not use farmyard manure that is not completely decomposed, do not use too much chemical fertilizer, otherwise it will burn roots and hurt seedlings, do not use sticky soil as seedbed soil, otherwise it is easy to rot rotten roots, and do not use soil with too loose soil as seedbed soil, otherwise it is easy to drought or freeze damage.
