Dry sowing and raising the "five customs"

Dedicated to the ground

Three days before sowing, Putian Mu applied 20 kg of compound fertilizer, 50 kg of superphosphate and 15 kg of potassium chloride as base fertilizer.

Soaking seeds and germination

Seeds should be strictly disinfected. Generally, 25 to 30 kg of soaked seeds with 0.01% potassium permanganate solution for 1 to 2 days, then keep warm and germination, and the seeds can be sown after breaking the chest.

Sowing at the right time

Early rice is usually planted in sunny days before and after the "shock".

When the seedbed management is closed, the seedling stage should be based on heat preservation and tidy emergence. The water management should master the surface of the seedbed if it is not whitish, or spray water. One leaf period to control the humidity, when the seedlings are in the same needle, it is best to use 0.2 g of paclobutrazol to 150 g of water per square meter for spray control. During the second leaf stage, dryness should be the main factor to promote deep rooting. During the three-leaf period, it should be kept moist. When the seedling grows to the second leaf and one heart, apply a “weaning fertilizer”, and use 8 kg of urea, 25 kg of superphosphate, and 6.5 kg of potassium chloride to make a 1% solution spray. Apply or drip, spray and rinse the seedlings after application.

Re-application of base fertilizer and timely transplanting

Generally, 1,500-2,000 kilograms of manure water, 10 kilograms of urea (or 20 kilograms of ammonium carbonate), 25 kilograms of superphosphate, and 5.5 kilograms of potassium chloride are applied. When the seedling grows to 4.5 leaves, grab the sunny day.
