Method for improving germination percentage of paspalum natatum in warm temperate zones

Abstract

The invention discloses a method for improving germination percentage of paspalum natatum in warm temperate zones, comprising the steps of: 1, pre-treating; 2, finishing; 3, sowing; and 4, managing after germinating. In the method disclosed by the invention, warm water is used to soak seeds for 4-5h, so that the wax coat is removed conveniently and safely, the feasibility is high, and the operation can be achieved in normal farms and pastures; concentrated sulfuric acid is dangerous when being used, the time is difficult to control, and the seeds are easy to carbonize carelessly, so that the result is failed; April and May are in blossoming spring in the warm temperate zones, and the climate is suitable, so the seeds are sowed in April and May, and the paspalum natatum germinates well; after the paspalum natatum germinates, the phosphatic fertilizer and fire ash mixed in the seeds provide sufficient phosphorus, potassium and nitrogen which are beneficial for growth of paspalum natatum seedlings; and therefore, the problem of low germination percentage is solved, the sufficient paspalum natatum seedlings are provided, can be widely planted and can be used for building lawns, growing pastures, fixing soil, protecting slope, and the like. The method provides a reliable guarantee for popularizing and planting the paspalum natatum in a large area.

Description

technical field

[0001] The invention belongs to the technical field of methods for increasing the germination rate of plants, in particular to a method for increasing the germination rate of bahia grass in warm temperate regions. Background technique

[0002] Bahia grass, also known as golden crown grass, scientific name Baja paspalum, is a world-renowned multi-purpose grass species, native to Latin America, the United States, Australia and other countries. The root is a fibrous root system, which spreads with the old stems and takes root when touching the soil. Most of the roots are concentrated in the 30-40 cm topsoil near the surface, and a few roots are as deep as 100-130 cm. The inflorescence is a raceme, heading and blooming from June to October, the flowering period is uneven, and the seeds mature one after another. The seeds are tightly wrapped with waxy glumes, which are not easy to absorb water. If untreated, the germination rate is extremely low. Bahia grass has...

Embodiment 1

[0010] The present invention solves the problem of low germination rate of bahia grass in warm temperate zone, comprising the following steps:

[0011] 1. Pre-treatment: Soak bahia grass seeds in warm water at 40 degrees Celsius for 4 hours, rub carefully with your hands to remove the waxy layer after soaking, keep the seeds moist after waxing, and keep them for no more than 48 hours;

[0012] 2. Sowing: From April to May, on the leeward and sunny plots, the soil is finely divided, built ridges, and small ridges with 1 meter ditch are built, and the seeds, phosphate fertilizer, and pyrotechnic ash after removing the wax layer Mix according to the ratio of 1:2:6, sow at a row spacing of 12 cm, cover soil thickness of 2 mm, keep the cover soil moist by spraying 3 times a day until germination;

[0013] 3. Management after germination: After 7 to 10 days, Bahia grass will start to germinate. After germination, continue to use spraying to keep the soil moist; weeds in the ground c...

[0015] 1. Pre-treatment: Soak bahia grass seeds in warm water at 45 degrees Celsius for 4.5 hours. After soaking, carefully rub the wax layer with your hands to remove the wax layer. After removing the wax, the seeds should be kept moist, and the storage time should not exceed 48 hours;

[0016] 2. Sowing: From April to May, on the leeward and sunny plots, the soil is finely divided, and ridges are built, and small ridges of 1.2 meters are built, and the seeds, phosphate fertilizer, and pyrotechnic ash after removing the wax layer Mix according to the ratio of 1:2:6, sow at a row spacing of 15 cm, cover soil thickness of 2.5 mm, keep the cover soil moist by spraying 4 times a day until germination;

[0017] 3. Management after germination: After 7 to 10 days, Bahia grass will start to germinate. After germination, continue to use spraying to keep the soil moist; weeds in the ground cannot be sprayed, and should be treated without tools as much as possible, and pulled out by han...

[0019] 1. Pre-treatment: Soak bahia grass seeds in warm water at 50 degrees Celsius for 5 hours. After soaking, use a flexible tool to carefully remove the wax layer. After removing the wax, the seeds should be kept moist, and the storage time should not exceed 48 hours;

[0020] 2. Sowing: From April to May, on the leeward and sunny plots, the soil is finely divided, built ridges, and small ridges with 1.5 meters of ditching are built, and the seeds, phosphate fertilizer, and pyrotechnic ash after the waxy layer are removed Mix evenly according to the ratio of 1:2:6, sow at a row spacing of 18 cm, cover soil thickness is 3 mm, keep the cover soil moist by spraying 5 times a day until germination;

[0021] 3. Management after germination: After 7 to 10 days, Bahia grass will start to germinate. After germination, continue to use spraying to keep the soil moist; weeds in the ground cannot be sprayed, and should be treated without tools as much as possible, and pulled out by hand...
