During the period of fruit expansion, the demand for water and fatty is high for plume grapes. In order to improve the quality of the fruit of the raisins, sufficient water fattening is provided during the expansion of the fruit, as well as management such as fruit fertilization and conservancy. The following is a presentation of fertilizer and management methods used during the mausoleum boom。
I. Fertilizer selection and fertilisation methods during the boom period of fruit
1. Fertilizer selection
The emphasis of fertilisation during the fertilisation period is on supplementing phosphorus, potassium, thereby contributing to the rapid expansion of the fruit cell and adding calcium to increase the hardness of the fruit. Magnesium cannot be lacking to prevent yellow leaves and fruits from becoming soft。
2. First expansion and hard core periods
The first expansion period, the rapid expansion of the berries, that is, the time between the flowering and the hard nuclei period, the berries will expand rapidly, and when the berries have soybeans, they will have to be followed by root fat. When berries have soybeans in size until the hard nucleum period, they are also sprayed with leaf fats rich in phosphorus and potassium。
During the rapid expansion of vegetative fruit, new and fast-growing leaf blades become deep green and have large palm plants, with a continuous application of 1 to 2 times of nitrogen fertilizer to the face of the leaf, with the use of 0. 1 to 0. 3 per cent urea, with a difference in the application of fertilizers to different strains. Two organic fermentations, such as fermented chicken dung。
3. Second boom period
After the second expansion, i. E. The hard core period, the berries become softer until the coloring period, and the berries become larger. In the early stages of chromatography, nitrogen phosphorus fertilisers are appropriate and can be applied from 5 to 8 kg of potassium phosphate per acre。
4. The maturity of berries
Peak grapes are grown early and late, usually blooming in late may and can mature in july. In the month preceding the harvest, 0. 3 per cent of potassium phosphate was sprayed twice every 15 days。
Ii. Management methodology for the energy period
1. Discovery
During the rapid expansion of the berries of the raisins, the berries need to be fertilized according to the size of the head of the berries, so as to promote the rapid expansion of the fruit by cutting out the small and thicker fruit that is not well developed, and ensuring that the fruit ears are finely organized, and that they are then able to grow into a cylindrical column, so that, as far as possible, the ripe fruit is about 0. 5 kg in weight and the fruit grain can reach 10 grams。
2. Appropriate use of plant growth regulators
During the rapid expansion of the larvae, appropriate use can be made of fruit expansion agents, such as hyperstatics and cactin, to achieve the porridge and promote berries expansion. In the 15 days following the graft, the inflatable agent can be sprayed or used for ingestion. The appropriate use of low concentrations of ethylene can be used for chromatography during chromatography。
3. Combating pests and diseases
Insects and insects of giant porridges, such as grey disease, albino disease, frost disease, corrosive brownness and green blindness, are harmful to fruit during periods of expansion, and can be prevented in a timely manner by combining kits。
Fruit packs
In order to prevent disease and control pesticide contamination, a bag should be made after twigs and use of the swelling agent, which could be used in general pulp bags, which would also ensure the beauty of fruit products. When the colouring period of the fruit is reached, the bags are properly released and the surrounding leaves and yellow leaves are removed。
Control of soil moisture
The period of expansion needs to be watered in time so that the fruits can grow as quickly as possible. A month before a mature harvest, water is properly controlled and can be provided in small quantities in the first 10 days, followed by a water stoppage in the following 15 to 20 days and drainage and drainage during rainy days。
