Please pay attention to the eight key points of mango flowers and fruits
In order to ensure the stable and high-yield planting of mango trees, it is crucial to manage the flowers and fruits during the flowering and fruit setting period. There are eight key points.
Finishing of flowering branches. Remove dense branches, shady and weak branches and diseased branches about 2 months before flower bud differentiation, leaving only 1 to 2 shoots per branch, which can increase the light transmittance of the canopy, which is conducive to the concentration of nutrients and the formation of good Ventilation and light conditions can promote flower bud differentiation and prevent pests and diseases.
Re-manage before and after flowering. Before the mango orchard blooms, pile up garbage or retort bran manure, chicken manure, salted fish fragments, poultry offal, etc. in the orchard, which can cultivate and attract flies to come to the orchard for reproduction and pollination. After blooming, if it encounters rainy weather, it is easy to produce retting, use artificial shaking of flower branches to shake off stagnant water; after blooming, strengthen the pruning of fruit trees, keep the crown of the tree ventilated and light, and should also combine the prevention and control of pests and diseases during the fruit setting period. Flies are killed in the whole garden.
Apply trace elements and calcium fertilizer. From flowering to young fruit stage, lime can be applied to reduce soil acidity and harmful iron, aluminum, and manganese content, and increase calcium levels. Generally, 0.6 to 0.8 kg of lime is applied to each plant, or 2% calcium chloride solution is sprayed from flowering to fruit setting. The application of zinc and boron can be sprayed with 0.2% zinc sulfate and 0.2% borax solution 10 days before flowering and after blooming and declining flowers to promote pollination and fruit setting.
Spray flowers and fruits. Use 50-100ppm gibberellin to spray once every 15-20 days after the flower fades for a total of 2 to 3 times, which has a certain effect on improving the fruit setting rate. Start one week before blooming, spray the canopy with "0.2% potassium dihydrogen phosphate + 0.2% borax + 0.3% urea mixture", spray once every 7 to 10 days, and spray 2 to 3 times continuously, which can improve the quality of inflorescence and The ratio of sex to flowers improves fruit setting.
Topdressing is performed outside the rhizosphere. Fertilizer should be added according to tree vigor and fruit amount after the flower fading to the rapid expansion of young fruit. For trees less than 10 years old, apply 0.3-0.5 kg of urea and potassium fertilizer for each tree; for trees over 10 years old, apply 0.5-1.0 kg of urea and potassium fertilizer for each tree. For trees with few results, no nitrogen fertilizer can be added, and only potassium fertilizer is added. Apply 0.3 to 1.0 kg of potassium fertilizer. During the fruit growth period, the weak trees with more fruit can also be supplemented with appropriate amounts of nitrogen and potassium fertilizers in June. In addition, spray 0.3% boric acid and 0.2-0.3% potassium dihydrogen phosphate once in the full flowering period, final flowering period, and young fruit period.
Thinning and pruning fruit branches. Within 15 to 30 days after flowering, the young fruits such as peanuts should be thinned. Only 2 to 4 fruits per panicle are retained. The center is the best place to retain. Choose larger ones with green color and strong growth vigor. Fruits, the remaining fruits are evenly distributed in the crown and between the branches. It is advisable that the fruits are not close together.
Spray medicament to promote coloring. For some varieties with good red peel, such as Hongmang No. 6, Aiwenmang, etc., during pruning in the mid-fruit period, the shady branches, diseased branches and other branches that cover the fruit are removed to make a fruit receive sufficient light and evenly colored. Spray 1 to 2 times with 70% nitrile sulfoquinone wettable powder before bagging the fruit to make the appearance of Aiwen mango ruddy. Spraying 50% benomyl wettable powder can promote skin tenderness and produce fruit powder. Spray 80% Sulfur wettable powder can promote the red-yellow color of the peel and produce fruit powder.
Put the bag in time after the fruit set is stable. The fruit development period of mango is the hot and rainy season. Fruit bagging is the best way to protect the fruit from diseases and insects. Spray sterilization and insecticide before bagging. You can also put the paper bag into the liquid medicine and use it after soaking it. After the bag is covered, it should be tied tightly. Leakage holes are left at the bottom of the bag to remove the water in the bag. The size of the mango bag varies depending on the variety. The general specifications are 22-30 cm long and 15-20 cm wide. The material of the paper bag can be composed of white wax paper, black kraft paper and non-woven fabric.

Sweet corn. The light green outer leaves of sweet corn are yellow grains, but also purple and yellow. The grains are small and round, the skin is thin and soft, tender, sweet and delicious.Contains carotene, zeaxanthin, with the effect of eye protection.
Sweet corn is most often boiled into soups. It is a favorite soup for children and adults, whether it is made into a clear corn soup with ribs or pureed with cream.
Corn is also a good choice for consumption during weight loss because of its high available energy. The metabolic energy of corn is 14.06 MJ/kg, with the highest being 15.06 MJ/kg, the highest of the cereal feeds. This is mainly due to the fact that there is very little crude fibre in corn, only 2%, while the nitrogen-free leachate is up to 72% and the digestibility is up to 90%; on the one hand, corn has a high crude fat content, between 3.5% and 4.5%.
So how do you cook a sweet corn?
1. Leave the leaves
If you strip the leaves off, the corn will lose nutrients and flavor when it cooks, so it's best to leave two thin leaves to make it easier to cook and have a nice aroma.
2. Soak
Soak the corn in cold water for 20 to 30 minutes before boiling, then boil it on high heat to give it a bit more chew.
3. Add salt
When the water is boiling, add a little salt to amplify the sweetness of the corn.
