The lettuce black spot disease can grow and develop in the range of 10-35 ° C, and the temperature is about 17 ° C(plastic nursery pots). Seeds were left on the disease-free plants, then immediately transferred to cold water, and then the seeds were removed and dried for sowing(4.33inch plastic nursery pots). It can also be seeded with 50% of the seed weight of 0.3% of the chlorhexidine wettable powder, or with 50% of the acesulfame powder of the seed weight of 0.4%.
If the main stem is rapidly pulled high, the plants tend to age and are not suitable for consumption(plastic nursery pots manufacturers). It has the characteristics of quick activity, fast leaves, early branching, and easy to grow into high-yield seedlings quickly. However, its root system is shallow, it has many ineffective branches, is easy to fall, and has a low rate of ear formation(plastic potting pots). Therefore, it is different from artificial hand inserted early rice in field management.(cheap plastic seedling plug tray manufacturers bolivia)
When 80% to 90% of the seedlings are sufficient, it is enough for 3 to 7 days before the seedlings(plastic nursery pots wholesale). Early rice jointing, booting, heading and flowering are the critical period of water demand, accounting for 40% to 50% of the total water consumption. During this period, the water layer should be kept 5-6 cm deep, and the water should be tempered to promote the various organs of rice(4.72inch plastic plant pots). Normal development, promote large ears, more grains, and increased yield.
When the plants are fully grown and not aged, they can be harvested at the right time and pulled out directly from the soil(wholesale nursery pots). During the vigorous growth period of the leaves, the amount of water required for harvesting is large, which is labor-saving and labor-saving. The fertilization of early rice transplanting should follow the principle of base fertilizer, early fatning, medium-term control and late supplementation(4.92inch plastic plant pots). Then when the lettuce is full, the pot can be picked.
(cheap plastic seedling plug tray manufacturers bolivia)After the rice is thrown, the shallow water seedlings are required(black plastic nursery pots). The shallow water layer is maintained during the flowering period to ensure that the heading is neat, which is conducive to pollination and fertilization and grain formation. The early rice is kept moist after grouting to ensure the normal supply of oxygen and water in the roots(4.72inch plastic nursery pots), to keep the leaves from rooting, to enhance the growth stamina of the early rice, and to obtain yellow silk bright stalks.
Applying fertilizer early(6.3inch plastic plant pots), about 7 days after transplanting, applying 8-10 kg of urea per acre and 5~7.5 kg of potash fertilizer to promote early growth and strong growth; after 20 days of throwing, drainage should be done in the field, and control of ineffective tillering; 25 to 28 days can be applied once with panicle fertilizer(5.12inch plastic plant pots), 4-5 kg of urea, 3 to 4 kg of potassium chloride, or 5 to 7.5 kg of BB fertilizer, which promotes large grains of grains.(cheap plastic seedling plug tray manufacturers bolivia)
Keep the shallow water for 3 to 5 days after the throwing(cell trays). When the seedlings are enough, drain the fields in time, control the ineffective tillers, and coordinate the growth. In order to obtain the late stalk, it is required to apply strong seed fertilizer at the beginning of the earing stage. It can spray 100-150 grams of potassium dihydrogen phosphate per acre or 2 to 3 kilograms of urea per acre(5.5inch plastic plant pots), and 2 to 3 kilograms of potassium chloride to promote grain.
(cheap plastic seedling plug tray manufacturers bolivia)The feet are pregnant with water and the flowers are shallow(4.33inch plastic plant pots). At the same time, spray "nine two o" (one gram per acre) to prevent the early rice from being thrown into the rice. The time for cultivating rice in the field is higher than that of hand-inserted rice. Full, improve the seed setting rate. Or the seeds are soaked in warm water at 50 °C for 25 minutes(5.9inch plastic plant pots). The second stage of normal panicle differentiation of normal transplanted early rice
