Sunflower pollination operations
Silent sunflowers
Because of the dignified resemblance of the sun, the bright colors and the characteristics of the sun-turning, the sunflower has always been a touch of romance in the writings of literati and ink writers. Sunflowers are native to the Americas and are one of the world's four largest oil crops. His varieties can be divided into two categories: "general ornamental" varieties or "edible" varieties: general ornamental plants are shorter and suitable for planting in potted plants; Edible varieties are taller and taller, generally planted in open-air nurseries, edible varieties as a cash crop, seeds can be used as a delicious snack, can be squeezed sunflower oil, oil residue can also be used as feed.
In addition to being an important cash crop, there is also a beautiful Greece legend about sunflowers. Cleita is a mizusawa nymph, and a chance encounter fascinates her with Apollo, the god of light, but Apollo does not notice Cleita at all, and she can only watch the sky every day, watching Apollo ride a golden day chariot across the sky. As soon as the sun rose, she looked at the sun and watched Apollo's journey intently until he descended. Later, the gods took pity on Cleita and turned her into a large golden sunflower. Her face became a flower plate, forever facing the sun, following Apollo every day. Therefore, the flower language of sunflowers is silent love.
Drone-assisted sunflower pollination
From seed selection to harvesting, the growth of each sunflower plant has to go through a lot of grinding. Sunflower is a cross-pollinated crop, and artificial assisted pollination can improve seed setting rate and significantly increase yield. When bees collect nectar and pollen, they will collect many flowers in a row, which is likely to cause poor pollination and uneven pollination, resulting in empty shells and incomplete particles of sunflowers. In order to harvest the full fruit, the pollination of sunflowers also needs special care. The drone spraying "pollination essence" can effectively assist in sunflower pollination and improve harvest.
From August to September this year, in Wuchuan County, Hohhot City, Inner Mongolia, Ulanqab City, Inner Mongolia, and Siziwangqi, Ulanqab City, Inner Mongolia, Inner Mongolia Hewen Plant Protection Team used MG-1 to spray "pollination essence" for sunflowers. "Pollination Serum" is a plant endogen that acts as a foliar spray to help pollinate sunflowers. After the essence is sprayed on the crop, it can be absorbed through the foliar surface and can be transmitted to all parts of the stem and root, promoting the coordinated development of vegetative growth and reproductive growth. The essence generally uses efficient and safe imported additives, which can accelerate the formation and development of organs, generate high-quality stamens, promote pollen tube elongation and pollen germination, and at the same time balance the ratio of male to female, maintain the durability of the fertilization process, and control the growth of nutrients. In addition, pollination essence can effectively improve the efficiency of photosynthesis, significantly improve the pod setting rate and fruit setting rate, promote fruit expansion, and prevent the generation of shell particles.
The MG-1 rotor UAV blades will form a turbulent area on the crops below when rotating, and the crops can be turned and shaken when spraying drugs, so some pesticides can be sprayed on the back of the stems and leaves, flower discs, which is the spraying quality that cannot be achieved by manual and other spraying equipment at present. Bees and other insects in nature do not pollinate enough, so artificial beekeeping is commonly needed in many places, but with drone-assisted pollination, there will be a replacement or greatly reduction of the possibility of specially raised bees for pollination. Due to the use of drones to assist pollination, it has the advantages of lower price, good effect, less time and uniform pollination than beehive pollination, and according to the feedback of farmers, the yield per mu increased by 12%-20% after using pollination essence. In the future, it is very likely that drones will completely replace bee pollination with pollination essence, and precision agriculture will be fully embodied.
Basic information on sunflower pollination
The children's shoes of various plant protection teams should pay special attention to the specific data of this operation case of Hewen in Inner Mongolia, come and take a look at the following dry goods!
Environmental information
Operation time: August 8, 2016 - September 8, 2016
Operation location: Wuchuan County, Hohhot City, Inner Mongolia, Ulanqab City, Inner Mongolia, Ulanqab City, Inner Mongolia Siziwang Banner
Operating weather: Winds within level 3, sunny weather
Operating temperature: about 23°C
Terrain: Dryland
Crop information
Crop type: edible
Crop growth period: before flowering and early flowering
Number of acres of operation: about 8000 acres
Age/Disease Description: None
Control object: sunflower seeds are hollow and not full
Medication information
Pesticide name: Blue Sky Chemical Pollination Essence
Dosage form: 15ml
Active ingredient and content: phenypeptaline acid, amino acid ≥ 100g/L, Fe + Mn + Zn + B ≥ 20g/L
Dosage per mu: 300ml pollination essence× 10L water (10 mu dosage, 30ml per mu of land, that is, 2 bags)
Operational parameters of plant protection machine
Flight altitude: 1.5m from sunflowers
Operation spray width: 5m
Flight speed: 5m/s
Spraying rate: 3
Price comparison
The drone service is 10 yuan for one acre of land, 10 yuan for a bag of pollination essence (2 bags of essence for one acre of land), and a total of 15,000 yuan for 500 acres of land.
Renting a box of bee pollination is 150 yuan (the price varies depending on the region), and renting 100-200 boxes for 500 acres of land, totaling 15,000-30,000 yuan.
Comparison of yield per mu
Bee pollination: 230~260kg/mu
Pollination essence: about 260~300kg/mu
With an average increase of about 30kg per mu, taking the price of 6 yuan per kilogram as an example, 1,000 mu of sunflower land with pollination essence can increase the profit of about 180,000 yuan for farmers.
