How to do cross-pollination in eggplant? A detailed explanation of the management technique key points
The most suitable temperature for eggplant flowering and fruiting is 25-30°C. Below 17°C or above 40°C, fertilization and fruiting cannot occur. The flowers open at around 6 a.m., and the anthers begin to split after 7 a.m., so the suitable pollination time each day is after 8 o'clock. For cross-pollination, on the afternoon of the day before the female parent's flower opens, select buds whose corolla has emerged to 1/2 of the bud, light purple, and not yet open, and emasculate them. Emasculation must be thorough to avoid false hybrids. On the next day, when the male parent's flowers open, collect pollen (pollination with pollen from flowers opening on the same day gives the highest fruit-setting rate), and smear the pollen onto the stigma of the female parent. The paired eggplant (2 fruits) and the four-door fruit (1 fruit) should be selected for crossing. After the crossed fruit sets, all other buds should be removed. According to experiments, repeated pollination can increase the seed yield of F1 (i.e., the first hybrid generation) by 10%.

Facility eggplant cultivation management: beware of common mistakes
In winter, when cultivating eggplant in facilities, vegetable growers still make some mistakes in the management process, which should be improved. Mistake one: not planting grafted seedlings in new greenhouses. Many vegetable growers believe that in newly built greenhouses there are few root-knot nematodes and few pathogens of Verticillium wilt, Fusarium wilt and bacterial wilt, so high yields can still be obtained without planting grafted eggplant seedlings, but...

January eggplant pest and disease control and management technical points
For eggplants raised as seedlings in early spring, the main focus is controlling soil-borne diseases: damping-off, Rhizoctonia rot and sclerotinia rot. To disinfect the seedbed soil, mix 50 kg of seedbed soil with 20 g of 68% Jinlei water-dispersible granules and 10 ml of 2.5% Shileshi suspension concentrate, sieve and blend the soil, then fill nutrient pots with it, or spread it over the seedling bed. During the seedling stage, spray 0.1%-0.2% monopotassium phosphate, ...

Detailed Explanation of Greenhouse Management Techniques for Sweet Cherry
1. Soil, Fertilizer and Water Management Sweet cherry is a shallow-rooted tree species with vigorous root respiration, so the requirements of water, fertilizer, air and heat needed for root growth should be met as much as possible. Each growing season requires at least 4 to 5 intertillages, with a depth of 5 to 10 cm being appropriate, which both removes weeds and preserves soil moisture, activates the soil and enhances permeability. After harvest, shallow plowing should be carried out...
