What are the latest management techniques for nectarine after harvest?
Nectarine is a very common fruit in our country. The taste of nectarine is slightly sour, but sweet within the sourness, and it is favored by many people. Therefore, the nectarine planting area in our country is now very extensive. Nectarine is a fruit that can be harvested for many years, and after harvest in the previous year, attention should be paid to doing a good job of management to ensure the yield and growth capacity of nectarines in the second year. So how should nectarines be managed after harvest? Let's take a look together below!
1. Fertilizer and water management
After the fruit is harvested, most of the nutrients in the tree body leave with the fruit. Therefore, in order to restore the growth vigor of the nectarine tree as soon as possible, promote the growth of new shoots, and strengthen the growth capacity of the roots, we should strengthen fertilizer and water management. When topdressing, mainly use nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer. Apply base fertilizer in autumn to help the nectarine trees overwinter. Then also water appropriately, which can not only meet the water demand of nectarines, but also improve fertilizer efficiency. However, pay attention to the amount to prevent water accumulation from damaging the roots. When fertilizing, combine it with land preparation work and fully mix the fertilizer with the soil.
2. Reasonable weeding
After harvest, attention must be paid to doing a good job of weeding. Because the roots of peach trees are not distributed deeply, if weeds are not removed in time, the weeds will snatch the nutrients of the peach trees, causing the recovery of the peach tree vigor to be blocked, affecting the sprouting of new shoots the next year, and reducing the flowering and fruiting rate. However, attention should also be paid to the weeding method. When weeding, mainly use manual pulling of weeds. This is also because the roots of peach trees are shallowly distributed. If chemical herbicides are used, they can easily affect the roots of peach trees and cause damage to the roots. This leads to early defoliation of peach trees, which not only fails to restore tree vigor, but also reduces tree vigor.
3. Control nitrogen fertilizer
Peach tree varieties are divided into three types: early, middle, and late maturing. When planting early maturing varieties, because their growth and maturity cycle is relatively short and the maturity time is also relatively early, the harvest time is generally in summer and other high-temperature and high-humidity environments. At this time, the growth and nutritional demand of peach trees is large. Although after harvest, nutrients need to be supplemented in time to promote flower bud differentiation to ensure the fruiting amount of the second crop, attention must be paid to controlling the amount of nitrogen fertilizer. Topdressing should mainly be phosphorus and potassium fertilizer to prevent excessive nitrogen fertilizer from causing vigorous growth of nectarine trees and affecting the flower bud differentiation of nectarines.
4. Pest and disease control
Pest and disease control is work that must be emphasized and done well no matter which period the nectarine is in. Because pests and diseases are very harmful to the growth of nectarine trees. If the control work is not done well, it will seriously reduce the flowering and fruiting rate of nectarine trees, leading to a serious decline in planting benefits. Therefore, we should strengthen management, focus on prevention, and understand the symptoms of some common pests and diseases of nectarines, so that corresponding measures can be taken in time after they occur. Prevent the disease from spreading and expanding the affected area.
The above is a brief introduction to how to manage nectarines after harvest. The management work of nectarines is very important and is closely related to our planting benefits, so everyone must pay more attention! That is all for today's introduction.
