Management technology of pollution-free and high-quality eggplant

Eggplant in the growth process, must do careful scientific field management, in order to delay plant decline, ensure continuous flowering, improve yield.

Eggplant fruit setting rules are generally increased with the branching of the plant, basically a fruit per branching. In planting management, we should make full use of this characteristic, and pick the core in time after planting to promote its rapid branching, increase the fruiting position and improve the fruit setting rate.

Eggplant plant growth weak, nutrition deficiency, will aggravate flower drop fruit; but growth too prosperous, but also will cause nutrition deficiency and cause flower drop fruit. Fruit setting of eggplant increased with the branching of the plant. After planting, it should be picked in time. Spraying Cuhuawang No.3 inhibited the vigorous growth of the main shoot, promoted the rapid branching of the plant, increased the fruiting position and increased the fruit setting rate. And timely topdressing irrigation before flowering, spraying Caiguozhuangdiling before flowering, young fruit stage, fruit expansion stage to increase nutrient delivery, inhibit shoot crazy growth, promote flowers, strong stems, improve fruit expansion vitality, at the same time spray new lipid membrane to form protective film, prevent airborne virus spread.

When strengthening fertilizer and water management for weak seedlings, organic fertilizer and available phosphorus should be mainly used in the early stage, and available nitrogen fertilizer should be used in the middle and late stages. It is best to apply 500-600 kg of decomposed thin manure per mu or 20-30 kg of cake fertilizer and add 15-20 kg of calcium superphosphate when flowering. After entering the full fruiting period, the topdressing should be mainly changed to quick-acting nitrogen fertilizer (urea 10-15 kg per mu), and 3-5 times in the fruiting period. Root irrigation with root application and micro-fertilizer in real time can induce plants to absorb, digest and release nitrogen, phosphorus, potassium and various trace elements in soil, improve positive energy of eggplant development and optimize eggplant quality.
