When will the eggplant be planted?

Eggplant is one of the favorite fruits and vegetables, and it is also one of the main vegetables in summer in our country. It is grown all over the country. The leaves, roots and stems of eggplant can be used as medicine and have high planting value. So, when will the eggplant be planted? How to plant it? Now let's take a look at the planting time and method of eggplant.

1. Planting time of eggplant

Eggplant is an annual herb, the growth temperature is between 20 degrees and 30 degrees, and the requirement of water and fertilizer is relatively high, so it is suitable for planting in early spring and early autumn. The early spring season. Eggplant can be planted from the end of December to the end of February in early spring; in early autumn. Eggplant in early autumn can be planted from the beginning of July to the end of August.

Second, the planting method of eggplant

1. Selection of improved varieties: at present, the eggplant varieties suitable for planting in Guangdong are mainly resistant to green and disease, heat and Rain Water, purplish red skin, white pulp and long stick shape. The varieties with fruit length of about 30 cm are Hongfeng, Changfeng, Zaofeng, Nongyou Chang eggplant, Guilin Changcheng eggplant, and those with fruit length of about 25 cm are Yueqie No. 2, Yuefeng and stele red eggplant. Among them, Hongfeng fruit is grown, uniform and beautiful in appearance. Yueqie No. 2 is a variety with high resistance to bacterial wilt and Verticillium wilt. Yuefeng and Shijie red eggplant have good dark gloss. Guilin long eggplant has high yield and disease resistance, but its pulp is blue.

two。 Land selection and preparation: nursery beds and planting sites should be selected as plots of non-eggplant crops, preferably paddy fields, deep ploughing and exposure, with a height of more than 30 centimeters. The border is wide and covers ditches, with 1.7 meters in double rows and 1 meters in single rows. The seedbed was sprayed with 500 times pentachloronitrobenzene or dichlorvos 500 times and 800 times dichlorvos 7-10 days before sowing and disinfected with film covering.

3. Apply sufficient base fertilizer: the planting site should apply sufficient base fertilizer. Generally, 1000-1500 kg of fully mature pig, cow and chicken manure, 80 kg of peanut bran, 50 kg of superphosphate and 80 kg of lime should be applied per mu. 1-2 days before sowing, 20 kg of fully mature fine farm manure plus compound fertilizer per mu was used as base fertilizer and fully mixed with topsoil.

4. Suitable sowing time: the suitable sowing time of spring eggplant is from late October to November, and the seedling stage is 60-70 days. The suitable sowing period of Kandelia Candel is from June to July and the seedling stage is 25-30 days. Anti-season cultivation in cold areas can be sowed from March to April and transplanted in May. The general seed consumption per mu is 15-20 grams.

5. Fertilizer and water management: ① re-application of base fertilizer. Combined with soil preparation, 15000-20000 kg of mature farm manure, 10-15 kg of urea and 50 kg of compound fertilizer (15 ∶ 15 ∶ 15) were applied every 667m2, and seedling fertilizer was applied lightly with ②. After planting to before flowering, topdressing 1-2 times according to the plant growth potential, the concentration should not be too high, otherwise it will cause the plant to grow excessively, resulting in falling flowers and fruits. During the pollination period, in order to prevent flower and fruit drop, if the plant is not seriously short of fertilizer and water, generally do not need topdressing and watering; ③ timely topdressing fruit fertilizer. When the pollination fruit grows to the size of duck eggs, timely watering and topdressing, 10-20 kg of urea and 25 kg of compound fertilizer are applied per mu to promote the rapid expansion of the fruit. After pollination, topdressing 2-3 times and applying compound fertilizer 10-15 kg per mu each time. Stop topdressing when the fruit begins to change color and keep the soil moist. The soil preparation and base fertilizer of the male parent field are basically the same as that of the mother Honda. As long as there is an adequate supply of pollen, generally no longer topdressing, to keep the soil moist.

6. Plant adjustment: in order to reduce the nutrient consumption, make the female parent plant blossom more in a short time, shorten the pollination time, and facilitate centralized pollination, it is necessary to remove the door eggplant flower bud and all the lateral branches below (middle and late maturity varieties can leave one side branch). Keep the plant bifurcated. After pollination, leave 3 leaves to top, insert bracket to prevent lodging and reduce rotten fruit.

7. De-pollination: strictly remove the miscellaneous plants of the father and mother in the field. The miscellaneous plants were removed mainly on the basis of the typicality of initial flower node, leaf shape, leaf color, growth and flower color of the parents. After pollination, remove the inbred fruit and male plant from the female parent plant.

8. Pest control: on eggplant pest control technology, please read the article "eggplant pest control technology", here the editor will not repeat it.

9. Seed collection and storage: 50-60 days after flowering, when the pericarp turns yellow (some varieties do not change color or slowly, depending on the days of pollination), the fruit will be ripe in a cool place for 7-10 days to collect seeds. When collecting hybrid fruit, check whether the pollination mark of hybrid fruit is obvious.

[conclusion] eggplant has high nutritional value and planting prospect. with the development of facility agriculture, the planting area of eggplant is also expanding. The above introduces the planting time and method of eggplant. I hope it can be helpful to you!
