What is the main factor affecting the quality of bitter gourd? What are its requirements for environmental conditions?

Bitter gourd is suitable for growing in high temperature and high humidity environment, and the germination temperature of seeds needs 30 ~ 35℃. Seedlings cannot grow below 10, and the whole breeding period needs 20 ~ 25℃. Results the relative humidity of the air needed after the machine was running was 80% ~ 85%. The light condition is not strict, and it can grow well under the conditions of high temperature, high humidity and poor light. Adaptability to soil and fertilizer is also suitable for plastic greenhouse planting. At present, there are two kinds of bitter gourd planted: white bitter gourd for vegetable and fruit, which is small in size, thin in skin and bitter. Plastic greenhouses should recruit 100 varieties. /kloc-more than 0/00 plants can grow to about 3 meters high, with thin stems and strong branches. Cucumber is 20-30 cm long, 4-5 cm horizontal, 4-52 species in a single family, with white epidermis and tumor-like protrusions. The flesh is white and the meat thickness is 0.8 ~ 1 cm. Green ripe cucumber has crisp and tender meat, moderate bitterness and good quality. 100 More than one state has less pests and diseases, strong heat tolerance, but poor cold tolerance.

Paocui: Bitter gourd has a thick seed coat and is not easy to germinate. When the water temperature is 20 ~ 25℃, soak it in hot water (sometimes boiled water) at 60~70℃ for 30~40 hours, then take it out and drain it. Bitter gourd with seedling age of about 60 days is precocious and has high yield. Therefore, it is necessary to cultivate seedlings in greenhouse around June 5438+1October 28. The sowing method is basically the same as other cucumbers, but the temperature management is 2 ~ 3 higher than other cucumbers. There is a saying in the mountain city of Chongqing called the stove. Chongqing people prefer to cook with bitter gourd in the Bible, and they prefer to clear away heat and relieve summer heat, which has become a healthy food for people. Momordica charantia root system is relatively developed and moist, which can not withstand collapse. It is planted beside ditches or lowlands and grows well. Stems are thin, branches are strong, mainly lateral bending, and lateral bending can occur, with dense terrains. Leaves palmately lobed or deeply lobed, green, smooth and glabrous. Flowers are solitary. Female spawning festivals vary from species to species. Usually, the first female bird occurs on the 8th to 20th day of the week, and the next 1-2 nodes are cancerous flowers, and then the cancerous flowers are regenerated every 3-7 nodes.

The shape of fruit varies from variety to variety, generally spindle-shaped, and there are many tumor-like protrusions on the surface of fruit. Fresh fruit or light green turns orange when it matures and is easy to crack. The fruit color is sweet, the seed skin is bright red, and there are about 30 cucumber sugar seeds. 1000-grain weight is about167g. Gibberellic acid and benzyl purine can inhibit buds and promote the formation of female flowers of bitter gourd. Low concentration of dwarf pigment shows female reaction, while high concentration of dwarf pigment shows male effect.

Bitter gourd has a hard seed coat and slow germination. Before sowing, it is usually soaked in warm water at 50 ~ 60℃ to cool down, and then soaked for 1 ~ 2 days to absorb water and expand to promote germination. After soaking, germinate, germinate and sow at 30 ~ 33℃. The sowing date of bitter gourd depends on the climatic conditions and supply demand in various places. Most provinces in the Yangtze River Basin sow saplings from late March to early April, and formally plant vegetation in late April. In order to quickly restore growth after meals, you can cultivate large seedlings and plant them in nutrient pots. Sow by stages with other varieties in the suburbs of Guangzhou, spring sowing in February and March, and the seedling stage is 20-40 days. Sow in summer from April to May, and the seedling stage is 4-5 days (cotyledon seedlings); The autumn broadcast is broadcast live by Cui Yahou and will be held in July and August.
