Cultivation techniques of Super Upland Rice 1

1. Intensive cultivation

The quality of cultivated land and soil preparation directly affects the whole seedling and the whole seedling of upland rice, as well as the ability of soil water conservation. Therefore, it is necessary to create a good environment for the growth and development of upland rice underground.

1.1. Deep ploughing: the suitable soil tillage depth for upland rice cultivation is 18cm to 20cm, but the depth of cultivated land must also be determined according to soil fertility and thickness.

1.2. Soil preparation: the requirement of intensive tillage is that the soil is flat, with four-sided ditches and middle ditches, which can drain and irrigate water, with a general ditch depth of 16 cm and a width of 33 cm. It is not appropriate to prepare the soil prematurely so as not to grow weeds. You can prepare the soil when sowing and sow immediately after the soil is refined. It is best to spray glyphosate or Nongda powerful herbicides 15 days in advance to remove weeds and control weeds before soil preparation in mountainous areas and barren plots.

2. Sowing seeds

The process before and after sowing is drying, soaking, medicine treatment, setting the sowing date, designing the sowing method, sowing in the right amount, covering soil and so on.
