Field management of Luohanguo

1. Build sheds, support vines and pick lateral buds. Siraitia grosvenorii is a kind of vine that needs scaffolding to climb. Only then can the plant grow well. After planting began to set up a shed, generally using bamboo as a support, the shed height of about 1.7m, the roof covered with small bamboo or branches, and then insert a small bamboo next to the plant, so that the stem vines climb up and grow.

When the seedling is high 17~20cm, the lateral branches growing on the vine stem are removed, leaving the main vine to facilitate the rapid growth of the main vine. When the seedling is high and 30cm, use straw or hemp rope to loosely bind the main vine to the bamboo to help the stem vine on the shed. If the vines on the shed fall, they must be helped up in time to facilitate the growth of the vines.

two。 Weeding and topdressing. Siraitia grosvenorii weeding and topdressing is carried out many times a year. During the period of seedling height 30cm from April to May, thin human manure was applied once, rotten stable manure and peanut bran were applied once after the main vine went up the shed in May, and during the flowering and fruiting period from June to September, mixed fertilizers such as barnyard manure, peanut bran and phosphate fertilizer were applied every 7-15 days to promote fruit growth. Fertilization method: open a semi-circular ditch at the top of the hillside away from the tuber 25cm. Do not apply fertilizer to the tuber.

3. Artificial pollination. Artificial pollination is an important technical measure in Siraitia grosvenorii production, which can increase plant fruit rate and yield. When the plant blossoms from June to July, the male flowers are picked every morning. Scrape the pollen with a bamboo stick and gently place the pollen on the stigma of the female flower. The pollen of each male flower can give about 10 female flowers. Artificial pollination ends in the morning, but the effect of afternoon pollination is poor. The pollen collected should be used on the same day. If you want to keep it until the next day, it must be dried and stored, otherwise it will lose its germinating power.

4. Anti-freezing, anti-dew. Every year in front of the Beginning of Winter, thicken the soil with 15cm and cover it with a layer of grass to prevent the tuber from freezing through the winter. Before and after the Qingming Festival in the second year, remove the mulch and peel off the soil to expose the tubers and dry them in the sun for 3-4 days. At the same time, cut off the withered vines to facilitate the growth of new buds.
