Five key points in the management of apricot trees after unloading fruit
First, thinning branches to remove the new apricot heads sprouting from the overdense perennial branches and backbone branches. Branches are evacuated and red apricots are full; branches are crowded and hanging is empty. Therefore, those who are in the wrong position and do not plan to be reserved for use as regeneration branches should be removed as soon as possible.

Measures for fertilizer and water management of apricot trees
The main results are as follows: 1. fertilizing young trees in the first year of planting, applying fertilizer with thin application, in order to rapidly expand the crown and form a certain number of flower buds. The first fertilizer was applied when it sprouted after planting, and then topdressing once every 15 ~ 20 days, mainly urea, combined with phosphorus, potash and organic fertilizer. Stop topdressing at the beginning of July and control it properly.

What are the environmental requirements for the growth of apricot trees?
Apricot is a perennial deciduous fruit tree with natural growth of more than 10 meters. It has a long life, like light, cold, drought and barren. It has strong adaptability to the external environmental conditions, and the range of suitable cultivation is also very wide. The average annual temperature in the main producing areas is-5-22 ℃, and the annual accumulated temperature above 10 ℃ ≥ is 1000-6500.

Soil testing and Formula fertilization Technology of Chestnut
1. The balance of the main branch (take the three main happy shape as an example). The main branch is the main skeleton that supports each branch. Before pruning, first take a closer look at the orientation and growth of the three main branches, and then adjust them after you have a good idea in mind. For strong and strong (large proportion of roughness) of the main branch, the angle can be enlarged, or the lateral branch can be used instead of the main branch to lengthen the head, combined with peeling.

Shaping and winter pruning of persimmon trees
Persimmon belongs to light-loving crops. Close planting should pay attention to ventilation and light transmission, which is the main measure of high-yield management. Persimmon results in axillary buds, so it is very important to remove strong long branches and strengthen nutrition accumulation of branches and stalks. It is very important to pay attention to amino acid coating before flowering, promote flower bud differentiation, overcome age, and promote early hanging fruit.

Control of root rot of papaya seedlings
Papaya is a subtropical crop, which is raised and transplanted. The analysis shows that the main causes of root rot at seedling stage are stagnant water in seedling bed after rain, high concentration of fertilization at seedling stage, invasion of nematodes and root rot pathogens. Prevention and control measures: 1. The root system of papaya should carry out respiration in the soil. Hypoxia under the condition of hypoxia.

Economic fertilizer application amount and suitable proportion of papaya trees
The amount of economic fertilizer application is the lowest amount of fertilizer application when high yield, high quality (or high economic benefit) is obtained due to the effect of fertilization. Practice has proved that, in a certain range, the yield and quality often improve with the increase of fertilizer application. However, when the amount of fertilizer application reaches a certain level, the yield and quality of fruit will increase with the amount of fertilizer application.
