Technical Field

The invention belongs to the technical field of saline-alkali tolerant rice planting, and particularly relates to a saline-alkali tolerant rice seedling raising substrate.

Background

The saline-alkali tolerant rice is perennial herbaceous plant, belongs to berry crops, and has the top yield in the world production of small berries. The saline-alkali tolerant rice is also an important economic crop in China, and according to statistics of food and agricultural organizations of the united nations, the saline-alkali tolerant rice accounts for 42% of sowing area of the world saline-alkali tolerant rice and 61% of yield of the world saline-alkali tolerant rice in 2012. Therefore, the planting of saline-alkali tolerant rice plays a very important role in the planting of Chinese economic crops.

The method is characterized in that the saline-alkali tolerant rice seedling culture time is generally from the beginning of field planting of a mother plant in the middle ten days of 4 months to the end of transplanting in the early 9 months of 8 months, three to four generations of sub plants are produced in each seedling culture period, and the sub-plants generated by the mother plant are transplanted in the seedling culture period of the mother plant. Generally, the earlier a parent plant becomes established, the greater the number of daughter plants produced under appropriate conditions. However, in the existing saline-alkali tolerant rice seedling raising process, the phenomenon of low and slow germination rate is caused by unreasonable nutrient input. Therefore, a seedling culture substrate designed aiming at the nutritional requirements of saline-alkali tolerant rice seedling culture is needed.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a saline-alkali tolerant rice seedling raising matrix, aiming at reducing insect pests and pesticide usage amount during soil cultivation, improving yield and reducing cost.

In order to achieve the purpose, the invention adopts the following technical scheme:

a saline-alkali-resistant rice seedling raising substrate comprises the following components in parts by weight: 10-12 parts of desulfurized gypsum, 1-2 parts of saline-alkali soil, 5-7 parts of straw powder, 3-5 parts of cassava residue, 20-35 parts of peat soil, 2-3 parts of ammonium sulfate and 1-2 parts of monopotassium phosphate.

On the basis of the scheme, the saline-alkali tolerant rice seedling raising substrate comprises the following components in parts by weight: 12 parts of desulfurized gypsum, 2 parts of saline-alkali soil, 6 parts of straw powder, 5 parts of cassava residue, 20 parts of peat soil, 3 parts of ammonium sulfate and 1 part of monopotassium phosphate.

On the basis of the scheme, the saline-alkali tolerant rice seedling raising substrate comprises the following components in parts by weight: 10 parts of desulfurized gypsum, 2 parts of saline-alkali soil, 5 parts of straw powder, 3 parts of cassava residue, 35 parts of peat soil, 2 parts of ammonium sulfate and 2 parts of potassium dihydrogen phosphate.
