Hybrid rice cultivation techniques

In order to capture the bumpy harvest, based on the use of conventional cultivation techniques, we must focus on “shortage seeding, short-term planting, shallow planting, shallow-irrigation control, and anti-rot control.” The specific cultivation techniques are as follows:

First, dilute short-lived

The amount of seed per mu is 2 pounds, and the paddy field is 0.1 mu. The transplanting time is 20-25 days. The suitable sowing date is from the end of May to the beginning of July.

Second, sparse shallow insert

It is required to plant 1.3-1.6 million clumps per acre, that is, a density of 6 inches and 7 inches, and even slightly increase the rice, it is best to use a wide line of narrow strains, east-west line to insert, when inserted as shallow as possible and stand seedlings, each clump 1 strain.

Three, shallow irrigation fertilizer

During the 15 days of transplanting, the field was lightly replanted twice a week, preferably during the day, and drained overnight. The amount of nitrogen fertilizer per acre should be controlled. Usually, topdressing urea is controlled within 25 kg per acre, and transplanting is carried out within two days of transplanting.

Fourth, to stop the music

In the tillering period and the booting period, attention should be paid to the prevention and control of various aphids, ie, heartworms, and pesticides such as rice straw and triazophos could be used for prevention and control according to pest information. Spraying jinggangmycin or Baoshouning 7 days before heading prevents folic acidosis during fruiting period.
