Planting time of eggplant

Eggplant was first produced in India and was introduced into China in the 4th-5th century A.D., with a cultivation area of more than 3 million mu, eggplant is one of the few purple vegetables, and it is also a very common household vegetable on the dinner table, with high planting value. let's take a look at the planting time of eggplant.

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.

1. Early spring season: eggplant in early spring can be planted from the end of December to the end of February.

2. Early autumn season: eggplant in early autumn can be planted from the beginning of July to the end of August.

Growth conditions of eggplant

1. Temperature: eggplant likes high temperature, the optimum temperature for seed germination is 25: 30 ℃, the optimum temperature for seedling development is 25: 30 ℃ during daytime, 15: 20 ℃ at night, and grows slowly below 15 ℃, causing flower drop. Metabolism disorder when it is lower than 10 ℃.

2. Light: eggplant has higher requirements for light time intensity. Under the condition of long sunshine and high intensity, eggplant has exuberant growth, good flower bud quality, high fruit yield and good coloring.

3. Moisture: less water is needed before the eggplant is formed, more water is needed after the eggplant grows rapidly, and the water demand is the largest before and after the eggplant harvest, so it should fully meet the water demand. Eggplant likes water and is afraid of water. When the soil is moist and ventilated, it is easy to cause retting roots, and the air humidity is easy to cause diseases.

4. Soil: it is suitable to be cultivated in the soil which is rich in organic matter and strong in water and fertilizer conservation. Eggplant has higher requirements for nitrogen fertilizer, delayed flower bud differentiation and significantly reduced flower number when nitrogen deficiency, especially in the peak flowering stage, if nitrogen deficiency, short-styled flowers become more, plant development is not good. Under the condition of low level of nitrogen fertilizer, the effect of phosphate fertilizer was not significant, and the absorption of potassium increased sharply in the later stage.

Sowing method of eggplant

1. Select 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.

2. Land selection and preparation: nursery beds and planting sites should be selected as plots of non-Solanaceae 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.
