The latest course of planting techniques and methods of Wang Bu Liu Lin

Vaccaria seed alias Vaccaria seed, wheat blue vegetable, etc., for carnation family plant wheat blue vegetable dry seed, medicinal with blood circulation, swelling pain, birth of milk function, wild born in wasteland, roadside, its drought resistance, barren resistance, can also grow together with wheat, adaptability is very strong, yield per mu stable between 150~300 kg, below we will take a look at Vaccaria seed planting technology bar!

Growth Habits of Vaccaria Seed

Vaccaria seeds like warm climate, the soil requirements are not strict, avoid flooding, if planted in low-lying areas, rainy season roots easy to rot, the ground gradually yellow □ death, serious or even no harvest. In excessively dry areas, plants grow stunted and yield low. Born in fields, roadsides, wasteland, most of them in wheat fields. China is distributed in Heilongjiang, Jilin, Liaoning, Hebei, Henan, Shanxi, Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Hunan, Hubei, Shaanxi, Gansu, Xinjiang, Yunnan, Sichuan and other places.

Seed Technology of Vaccaria Seed

1. Seed selection and sowing: Vaccaria seeds are usually propagated by seeds. When selecting seeds, full, shiny and black mature seeds should be selected. After drying, they should be stored. The sowing time should be set from mid-September to early October after the autumn crops begin to crop. Sowing in mid-April in northern areas can also be planted in spring and harvested in summer.

2, land preparation: Vaccaria seed planting should choose mountain gentle slope and good drainage sandy loam and clay loam, land selection should be combined with autumn tillage application of decomposed base fertilizer, 3000~4000 kg per mu, such as the simultaneous application of calcium superphosphate 20~30 kg can improve seed yield.

3. Sowing method: Vaccaria seeds can be seeded or drilled. The seeds can be seeded on the whole ridge surface. The holes are dug according to the row spacing of 25×20 cm, and the hole depth is 3~5 cm. Then, according to the seed amount of 1 kg per mu, the seeds are mixed with plant ash and human and animal dung water to make seed ash, and 1 small pinch is evenly sprinkled into each hole. After sowing, the seed is covered with fine fertile soil with a thickness of 1~2 cm. According to the row spacing of 25~30 cm, shallow ditches are opened, and the depth of the ditches is about 3 cm. Then the seed ash is evenly scattered into the ditches. After sowing, the fine soil is covered with 1.5~2 cm, and the seed amount per mu is about 1.5 kg.

Cultivation techniques of Vaccaria seed

1. Intertillage and weeding: When the seed height of Vaccaria is 7~10 cm, carry out the first intertillage and weeding. It is advisable to loosen the soil shallow to avoid damaging the roots and remove the weeds by hand. Combined with intertillage and weeding, thinning and supplementing seedlings were carried out, and 4~5 seedlings were reserved for each hole. The seedlings are thinned out at 15 cm spacing. If there is a lack of plants, use the seedlings to supplement the seedlings. The second time of intertillage weeding is carried out in February to March of the second year in combination with seedling determination.

2, timely topdressing: Vaccaria topdressing is generally carried out 2 to 3 times. For the first time, when the seedling height is 7~10 cm, after intertillage and weeding, 1500 kg of thin human and animal manure water or 5 kg of urea are applied per mu. After intertillage and weeding in spring of the second year, apply 2000 kg of concentrated human and animal manure water and 20 kg of calcium superphosphate per mu, or apply 0.2% potassium dihydrogen phosphate solution to the root for 1~2 times, which is beneficial to increase yield.

3, pest control: Vaccaria seed leaf spot disease to increase phosphorus, potassium fertilizer, or spray 0.2% potassium dihydrogen phosphate solution on the leaves to enhance the disease resistance of the plant. spray 500 - 600 times solution of 65% zineb, or 800 - 1000 time solution of 50% carbendazim, or 1:1:100 bordeaux mixture at that early stage of disease, spraying once every 7 - 10 days, continuously spraying 2 - 3 times. Fruit borer larvae harm fruit, with 90% trichlorfon 1000 times or 80% dichlorvos 1000 times spray kill.

4, harvesting and processing: Vaccaria seeds in the autumn after the second year of April to May harvest, generally in the seeds most become yellow brown, a few have become black when the ground part of the ground should be cut off in time. Harvesting too late, seeds fall off easily and are difficult to collect. After being cut back, the seeds are placed in a ventilated and dry place for ripening for 5 to 7 days, and when the seeds are completely blackened, they are dried in the sun, threshed, shaken to remove impurities, and then dried completely to obtain commodities. If mixed with wheat, it can be harvested together with wheat.
