A course on the cultivation techniques of the latest regenerated eggplant
Eggplant has the ability to regenerate old plants. at present, this cultivation technique has become a new problem in planting eggplant. Regeneration cultivation is a planting method that can increase yield. Eggplant can be renewed in the period of eggplant fruit, so that eggplant can continue to bear fruit. This can save cost, manpower and material resources, so it is a good cultivation method. However, there is not much experience in regenerative cultivation, so let's introduce this method in detail.
1. Pruning
In order to expand the fruit and concentrate nutrition, first leave a main branch and side branch on both sides of the door eggplant, then remove all the other side branches, leave two bifurcations, leave a pair of side branches below after forming a pair of eggplant, the rest are removed, and there are four retained bifurcations, also known as four doors, and then continue to retain a pair of side branches, other removal. Then you can stop pruning.
2. Pruning
After the old plant blossoms, it pinches the tip, and then fertilizes about 30 jin of high nitrogen fertilizer per mu. In July, when the eggplant market is at its peak, cut off the double branches in the upper part of the plant, leaving only the base or bifurcation of the plant, and then leave a few full buds on each plant to remove the other buds.
3. Strengthen the management
Pull out weeds, remove all kinds of withered branches and old leaves, and pay attention to the prevention and control of diseases and insect pests. It is necessary to timely watering and moisturizing, building shading net to shade, watering combined with fertilization, mainly composting with high humus content. This promotes the growth of buds and roots. When the eggplant is re-fruited, about 60 jin of compound fertilizer per mu will result in watering once a week at most. In order to prolong the growth, 20 jin of potash fertilizer and 30 jin of nitrogen fertilizer can be added.
4. Disease and pest control
The occurrence of Botrytis cinerea, one mu of Bacillus subtilis, 20 grams diluted 300 times spray. Cotton blight, which mainly harms fruits and sudden death of seedlings. If the high temperature occurs after rain, use 500 times of 70% manganese zinc ethyl aluminum wettable powder or 600 times of 70% propane zinc wettable powder. Sclerotinia sclerotiorum can be sprayed 1500 times the solution of 50% isobaric urea wettable powder at the flowering stage of door eggplant and eggplant. If red spider damage occurs, it can be killed by spraying 1000 times of 20% mite EC.
In fact, eggplant regeneration cultivation is the old plant regeneration cultivation technique, which is mainly to prolong the time limit of eggplant fruit. Through the way of pruning and rejuvenation to prolong and reduce the time of replanting, but the regeneration cultivation technology also needs certain climatic conditions, generally planting in the greenhouse.
