Seed cultivation of snow lotus root in Yugoslavia

The seed cultivation of snow lotus root in Yugoslavia can be divided into sexual reproduction and asexual reproduction. Sexual reproduction: refers to directly using the seeds of lotus root to cultivate seedlings. First, the grooved end of the lotus seed will break the pericarp and put it into 20-30 ℃ water to soak and accelerate budding. During this period, the water needs to be changed many times. Wait for the seeds to grow 4 leaves and 1 whip before transplanting. Asexual reproduction: the whole lotus root, seed lotus root or lotus root head is used as seed for colonization, which should be carried out when the temperature rises above 15 ℃.

I. seed planting of snow lotus root in Yugoslavia

1. Sexual reproduction

The main results are as follows: (1) sexual reproduction is the method of directly cultivating lotus root seeds into seedlings.

(2) first, the pericarp of the grooved end of the lotus seed was treated by hole-breaking, and then it was soaked in 20-30 ℃ water to accelerate budding.

(3) in the process of soaking and sprouting, the water needs to be changed frequently.

(4) after the seed has grown 4 leaves and 1 whip, it can be transplanted into the field.

2. Asexual reproduction

The main results are as follows: (1) asexual reproduction is the most commonly used method in daily planting of lotus root, that is, the whole lotus root, seed lotus root or lotus root head is used as seed for planting.

(2) this kind of breeding method usually chooses the temperature to rise above 15 ℃ when planting.

(3) the planting density should be determined according to the variety and the fat and thin of the field, the density of early-maturing variety is as high as possible, the density of late-maturing variety is sparse, the fertile field is a little thin, and the lean field is slightly dense.

(4) the row spacing of each plant is about 200 to 200 feet, and about 400 seeds can be planted per mu.

(5) when planting, the front part of the lotus root needs to be obliquely inserted in the soil, and the tail can be out of the water.

Second, the cultivation time of snow lotus root in Yugoslavia

1. Because the snow lotus root likes the warm and humid environment, so the cultivation generally chooses the hot and rainy season.

2. It can be cultivated when the temperature is more than 12-15 ℃ as far as possible.

3. The cultivation time is different in different regions, and the timely cultivation principle should be followed. The Yangtze River Basin is generally from late March to late April, while the Pearl River Basin is from late February to late March, and the northern region is from late April to late May.

4. The principle of "early rather than late" should be followed when cultivating snow lotus root, because early cultivation can adapt to the new environment as soon as possible and prolong the growth cycle.

Third, how to plant Yugoslav snow lotus root in mountainous areas

1. in the construction of lotus root pond, try to choose sunny and shady hilltop open land or village head wasteland, barren houses, waste pits and ponds, saline-alkali land, waterlogged land and so on.

2. The area of the lotus root pond needs to reach 200-300 inches, and the depth of the pool needs to be 60 cm.

3. Before planting, you need to sprinkle the lime into the pool and rotate it with a rotary plough for 2-3 times to make the lime and soil mix evenly.

4. The soil and ash are evenly mixed, and then the bottom and wall of the pool are mechanically leveled and compacted, and the wall is generally compacted in the proportion of lime and soil at 3:7.

5. Spread the bottom and wall of the pool with thin film, and then flatten the pool with 2-3 cm thick concrete.

6. Then fill the pond with clay loam rich in organic matter, and wheat straw, corn stalk or weeds can be laid at the bottom of the pool before planting to achieve the effect of subsequent fattening.
