Beans, melons, eggplants and other vegetables are ready to be planted, how to keep them to increase

Beans, melons, eggplants and other vegetables are ready to be planted, how to keep them to increase the yield and income of vegetables?

1. Preservation technology of bean and vegetable seeds.

Common beans and vegetables in life include beans, cowpeas, kidney beans, soybeans and other varieties. As long as the crop grows well, yields well, and tastes good, you can choose to keep it.

The skills are as follows: After the beans are planted and poded, be sure to pay attention to the observation. Do not pluck beans from the first flower.

This bean is easy to distinguish as it is often close to the ground. In autumn, observe the bean skin. If they start to dry out, it means they can be plucked and then plucked again.

Thread all the beans and their skins together and place them in a cool, ventilated place. Next spring, take off the beans, peel them off, and you're ready to sow the seeds. Reason:

The first seed, the bottom of the bean, can make the pod.

Flowering, and bottom-up fruiting at the later stages of planting to ensure yields. Seeds in other locations will move the pods upwards, greatly reducing yields.

2. Eggplant, fruit and vegetable preservation technology.

Eggplant vegetables typically include tomatoes, eggplants, peppers, and other varieties. There are a lot of vegetable seeds here, and many people often choose to preserve large fruits when harvesting. I don't think there's anything wrong with it, but it will affect next year's production.

Here's the tip: Whether it's peppers, eggplants, or tomato seedlings, keep the first and second fruits for later planting. Observe the changes in the remaining fruits.

If the ** is aged or the color turns red, it should be picked in time; Again, string the seeds together with a thread and then remove, ventilate and dry before preservation. Reason: eggplant fruits and vegetables, the first fruit can ensure early ripening, increase the fruit opening time, and the yield will naturally be high; The seeds of other stages are just the opposite.

How to preserve melon vegetable seeds.

Melon vegetables include: cucumber, loofah, pumpkin, bitter gourd, winter melon, etc. These vegetables can also be grown on their own.

Growing melon crops also requires skill. If you don't master these skills well, both yield and quality will suffer. Let's see how to grow melon crops.

After the melon crop emerges, it is necessary to choose a strong and lush plant, and then choose a melon with good shape, large body and close to the roots. The best is the second melon close to the roots. If the first melon is in good shape, it can also be kept, and the third melon will not be left.

In autumn, when the skin of the melon turns yellow and hard, pick the melon seeds that have been planted, cut them, take out the seeds inside, rinse them with water, then dry them, and store them in a breathable cloth bag. Experience has shown that the first and second watermelons near the roots ripen very early after planting, and there are more watermelons. Starting from the third melon, the melon is late and the melon is less.

Beans, melons, eggplants and other vegetables can be left by themselves, and the fruits that grow from the first flower should be selected when leaving the seeds, and then they will be retained, and finally the retained seeds can be screened, so as to ensure the yield of vegetables in the coming year.

No matter what crops are planted, strong seedlings are the basis of later yields, and if there is no strong seedlings, there will be no yield in the later stage, so cultivating strong seedlings is the top priority in planting. In addition to controlling water and squatting seedlings after the seedlings are set to promote root rooting, it is also necessary to use biotechnology to promote the development of the root system and the seedlings to be strong. When many people plant vegetables, they generally fertilize very much, and when they are in the middle of growth, the seedlings will grow too lush, which is very unfavorable for flowering and fruiting, because the plant grows vigorously, it will compete with flowering and fruiting for nutrients, which will lead to less flowering, less fruit, and even the flowers have fallen, and there are not a few fruits on the pillar at the end, so in the middle period, that is, from the flowering period to the fruiting period, this period of time can not let the branches and leaves grow, but also let him bloom more and bear more fruit.

Beans, melons, eggplants and other vegetables must be selected to have a good fruit shape, high yield, and many fruits.

Thread all the beans together with the skin, place them in a cool and ventilated place, and observe the changes in the fruit left, and pick them off in time if the skin is old or the color turns red.

Be sure to choose plants that are vigorous, then be sure to strengthen management, mark shoes that are free of pests and diseases, prevent insect infestations, and then wait until the eggplant is ripe to tie the eggplant, plane, and then remove the seeds.

Choose eggplants that are growing well, and then shake out all the seeds inside, and choose the ones that are full of grains.

To enhance photosynthesis and improve photosynthetic production efficiency, we need to start from the following aspects.

It is to increase the light transmittance of the lighting surface of the greenhouse, improve the light conditions, and make full use of light energy. Light is the energy of photosynthesis**, the intensity of light in the greenhouse, and the length of time to see light are the main factors that determine the level of photosynthetic production. Maximizing the use of light energy is not only the main condition for plants to increase photosynthetic production, but also the heat of the greenhouse in cold weather conditions**.

In addition to seasonal changes, indoor light intensity is also affected by the shape and angle of the greenhouse light transmittance surface, the type and condition of plastic film, the greenhouse support and population structure, etc. According to the research of Professor Xing Yuxian of Shandong Agricultural University, with the change of the angle between the slope surface and the ground, the solar transmittance and incident energy change significantly. In the three months from December to February of the following year, when the daylight surface is 10 degrees, the noon sunlight incidence is 6467 kJ meters for 2 hours; When the daylighting surface is 20 degrees, the incidence of sunlight is 7557 kJ meters for 2 hours, which is higher than that at 10 degrees; When the daylighting surface is 30 degrees, the incidence of sunlight is kilojoules for 2 hours, which is higher than that at 20 degrees; And at 40 degrees, the increase is even more.

Therefore, when we build greenhouses, under the premise of not affecting the windproof and thermal insulation performance, as long as the conditions permit, the larger the angle of the light transmission surface, the more conducive to light transmission. In addition, as mentioned above, the shape of the lighting surface, the type and condition of the film, the projection ratio of the lighting surface to the rear slope surface, and the hanging of reflective curtains can all significantly affect the lighting conditions in the greenhouse.
