First, prepare the seedbed
Prepare bed soil, choose fertile loam as good, account for about 60% of the total amount, 30% of decomposed organic fertilizer, about 10% of ternary compound fertilizer, spread the three evenly and spread on the seedbed, Hey, generally 6 meters long and 1.5 meters wide. Medicinal earth was prepared and mixed with 70% of pentachloronitrobenzene powder and 65% of zein zinc powder. Mix 70-80 g and 150 kg of fine soil with each well and mix them until ready for use.
Second, choose the best species
Cold spring shed cultivation in early spring should use varieties with good precocity, low temperature resistance, strong disease resistance and high yield, such as Zhongjiao No.7 and Jinjiao No.4.
Third, the seed disinfection
With 80% mancozeb (0.3% of the seed weight), the seeds and reagents were placed in a sealed jar or plastic bag, and the powder was evenly applied to the seed coat after shaking for 5 minutes. Prevents early stage blight and damping-off.
Fourth, timely sowing
It is generally appropriate to sow in the middle or late December. Before planting, seedlings should be covered with plastic film and straw to increase the temperature inside the nursery bed. Sowing should be selected sunny, the day before the bottom water, the next day will be prepared medicine with 2/3 evenly sprinkled in the pot, the rest of the drug soil covered in the above, you can also leave a small amount of drug soil after filling joints. Use 150 grams per mu. After sowing, sprinkle some poison baits in the cockroach to kill and kill cockroaches. Every day at 10 am, we open the haystacks and lay down at 3-4pm. If the weather is bad, we must open it later. Seedlings begin to unearth in about 30 days, and generally do not need watering. If it is dry, use a sprayer to spray a small amount of warm water. When the seedlings grow to 6-8 leaves, if the room temperature exceeds 30°C, the air should be released in time. Ventilation mouth should be small to large to prevent injury, but also to prevent leggy. In the week before planting, the seedlings should be cultivated, and at the same time, grass seedlings can be avoided. As long as there is no frost, the last two days and nights do not close the air outlet to adapt to the outside weather conditions. In addition, as little rooting as possible when planting, shorten the time of seedlings.
