Virgin fruit has high nutritional value and unique flavor, and has the best of both food and ornament. it not only has bright color and beautiful shape, but also tastes palatable and nutritious. In addition to all the nutrients of tomato, its vitamin content is 1.7 times that of ordinary tomato. It has very high planting value. Let's take a look at when the virgin fruit is planted.

Planting time of virgin fruit

The suitable temperature for the growth and development of virgin fruit is 23: 28 ℃, and the night temperature is 15: 18 ℃. It likes sufficient sunlight and requires 60-80% soil moisture. It is suitable for slightly acidic soil with deep, loose and fertile soil layer and 6-6. 5 PH. Strong adaptability, through different sowing dates, the use of different facilities cultivation, can achieve four seasons production, annual supply. Usually spring sowing from April to June or autumn sowing from August to September in the north, spring sowing from February to June or autumn sowing from August to October in the south, and field planting from August to February of the following year.

Sowing and raising seedlings of virgin fruit

The seeds of virgin fruit should be disinfected before sowing. To control tomato early blight, soak the seeds in warm water for 3-4 hours, then soak them in 40% formalin 100 times solution, remove them 20 minutes later and seal them for 2-3 hours, and finally rinse them with clean water. To prevent and cure tomato virus disease, first soak in clean water for 3 hours for 4 hours, then transfer to 10% trisodium phosphate or 2% sodium hydroxide aqueous solution, soak for 20 minutes, rinse with clean water several times, and then test that pH is neutral. When sowing, the seedbed is first drenched with bottom water, mixed with fine sand or broken soil, sprinkled evenly on the seedbed and covered with loose soil 0.5 cm thick. Interseedling should be carried out when the seedlings grow 2-3 true leaves, and 5-6 true leaves can be transplanted.

Land preparation transplantation of virgin fruit

The virgin fruit planting land selects the fields with no Solanaceae plants planted in the previous crop and convenient for drainage and irrigation. After the land is ploughed and raked, the planting ditch is opened according to the row spacing, and the base fertilizer is applied to make a high border. The border is 1.4 to 1.7 meters wide (ditch), and the plant spacing is 45 to 55 centimeters. It is planted between 1600 and 2000 plants per mu, and strong seedlings are selected and irrigated immediately after planting.

Field management of virgin fruit

1. Rational fertilization: the root system of virgin fruit is developed, the growth is exuberant, and the fertilizer is mainly organic fertilizer, combined with compound fertilizer, 2500 kg of manure per mu, or 2000 kg of human and animal manure or 100kg of vegetable cake, 30kg of compound fertilizer and 50kg of calcium superphosphate are used as base fertilizer, and the growth is adjusted by water management. when harvesting the fruit before harvest, each harvest of 2 to 3 canopy fruit, according to the growth strength, topdressing liquid fertilizer for 2 times. However, an appropriate amount of potash fertilizer should be applied.

2. Reasonable irrigation: the virgin fruit is a vegetable crop that blossoms and bears fruit continuously. After entering the flowering stage, the principle of seeing wet and dry should be grasped (refers to watering once thoroughly, and then watering the second time when the soil is almost dry. The function is to prevent excessive watering leading to rotten roots and diseases and insect pests caused by moisture), not more watering, nor drought, otherwise it will cause falling flowers and fruits and physiological cracking.

3. Rack binding vine: the vine should be inserted in time after planting. The height of the precocious self-capping variety frame is less than 1 meter, and the height of the elevated variety frame is more than 1.5 meters. Generally insert herringbone frame and stand, frame pole should be strong and firm, in order to prevent lodging. Tie the vine from the upper part of the first ear and tie the stem to the rack, and then tie it every 2 to 3 leaves. Pay attention to the loosening of the vine, tighten the plant when it is prosperous, and loosen the weak one.

3, pruning and branching: according to the growth of virgin fruit, it can be divided into two methods: single stem pruning and double trunk pruning, single trunk only leaves main stem, and all lateral buds are removed, double trunk pruning is except trunk, leaving only one side branch from leaf axil below the first inflorescence, other lateral buds are all erased, picking buds should be carried out as soon as possible, it is best to choose sunny days. Keep the wound dry to avoid bacterial infection. if it is carried out on a rainy day, spray immediately after the operation.

4. Timely harvest: the virgin fruit should be harvested immediately when it is ripe according to the characteristics of different varieties, and the over-ripe harvest is not conducive to storage and transportation.
