1. Cucumbers can generally be selected according to the requirements of the same types of cucumber as early and late. Early maturing varieties should be selected as the first female flower with low node, melon yards, short internodes, and robust growth. The mid-late and late-maturing varieties should be selected for strong growth and strong disease resistance, and the first female flower should have the node and the berry yard density that meet the characteristics of the selected breeding cultivar, and be marked. Each plant can leave one or two; The condition of melon should be positive, long, straight, uniform, thick and thin, and the skin-colored thorn squid conforms to the characteristics of the selected species; the middle and late-maturing varieties can also be selected for the melons and be marked, and the species should be removed in time. The rest of melons. When the peel of cucumber fruits and melons becomes yellow-brown and there are small cracks, it is the best time for timely harvesting. The harvested cucumbers should be placed in a sheltered place sheltered from the rain, so that they can be cooked for seven or eight days. When the skin of the cucumber is all orange, it can be washed. After the seeds are dried, they can be put in cloth bags and stored in a cool, dry place. 2, green peppers can be selected during the growth period short, thick stems, leaves large, round and green leaves for planting strains. Then, in the seedlings, the plant type was compact and upright, the stem was bent down, the fruit drooped, the ripening was early, there were no pests, the thickness of the flesh was thick, and the color had the typical characteristics of the selected varieties, and the seeds with more set fruits and the upper and lower fruits were consistent. Each plant leaves three or four fruit, and the remaining fruit should be removed. When the red pericarp of the seed fruit becomes soft, timely harvest. The harvested fruits can be stringed together, hung in a ventilated place, and cooked for eight or nine days. Then the pods are taken for seeding. After the seeds are dried, they are put into a cloth bag and stored in cool, dry place. 3, eggplant is first in the production of seedlings for seedling selection, strain selection and fruit selection. The plants with robust growth and no pests were selected, and the main traits that were consistent with the characteristics of the varieties were used as seedlings. General late-maturing varieties, each plant selected two pairs of tomato as a tomato. For early maturing varieties, two pairs of eggplants and one or two “four-sided fruits†can be selected for each kind of eggplant, and the other eggplants should be collected early to speed up the growth of eggplant and mature early. The appropriate time for harvesting eggplants is that the eggplants are yellowish-brown or golden yellow and can be harvested when the hands are soft. After harvesting, the species of eggplant needs to be placed in a shaded place and piled up; the seeds are picked after about 7 days of ripening. After the seeds are dried, they are put into a bag and stored in a cool, dry place.
