The fragrance is a chilly and hot vegetable, and if the temperature is over 30 degrees, the growth rate of the fragrance will slow, so when the fragrance is grown in the summer, particular attention will be paid to temperature control, and the price of the fragrance sold in the summer is higher
1. Choice of varieties
Because spices are cold and insatiable to high temperatures, varieties that are drought-resistant, sun-tolerant, smoke late and grow faster should be chosen. Good and bad varieties also affect the production and quality of spices。
Selection of plots
Chaciculture is also grown on the basis of soil that is more fertile, water-preserving, drought-fed, water-fed, and, preferably, on plots that have not grown in more than three years。
3. Fertilizing the whole area
The fragrance harvest is more frequent and soil-based fertilizer must be sufficient. Precipient acres are grown to be 4,000 kg fat and 100 kg fat. Precipient crop residues should be removed to reduce the incidence of pests and diseases. Cultivated 1 to 1. 5 metres wide。
Seed treatment
Before planting, seeds need to be sprung, and the cuisine that sows is well and quickly. It is sufficient to sow 24 to 30 hours with fresh water, to extract it and spread it on wet sacks and to seed it in an environment of 20°c ~ 25°c。
Seeding
This can be done by stripping or sowing, with an acreage of about 2-3 kg per acre. Seeds are planted with a thin layer of soil, water, and some straw, straw, etc. Can be covered to maintain soil moisture. It's usually about 10 days a week or so before the cuisine comes out. Remember to cover the sunnet after planting in the summer to avoid high temperatures affecting the growth of fragrances。
6. Field management
(1) saplings and seedlings
In a week after that, the seedlings begin to grow, leaving strong seedlings to remove the weak. Keep the distance between plants at about 3 cm。
(2) fertilizer management
Fertilizer water management during the shrunk season is less watered in the preceding period, is more watered in the later period, is based on nitrogen fertilizer and can be washed with water, such as urea and septic water. In addition, leaves can be sprayed once every 7-10 days to promote growth and increase production。
(3) weeding
Clean up the weeds in time for the fragrance to grow, and ensure that the fragrances follow。
(4) pest management
The aphids are more likely to breed in the summer because of their special odour, their relatively small pests, and if 10 per cent of the aphids are sprayed with 800 times the solution after the aphid's hazard, they are sprayed every 10 days for two or three consecutive times。
